Here are our latest updates on Senate races around the country. CQ Politics is changing its rating on the Mississippi race, where Republican Roger Wicker, who was appointed to fill out Trent Lott's term, is seeking re-election from "No Clear Favorite" to "Leans Republican." In the Georgia contest between first term Republican Saxby Chambliss and Democrat Jim Martin, we are changing that rating from "Leans Republican" to "No Clear Favorite."

In contrast to a Fox News poll earlier today that saw Barack Obama's lead narrowing, a New York Times/CBS News poll conducted Oct. 25-29 has Obama still ahead by double-digits, leading 52 percent to 41 percent among likely voters with 5 percent undecided. The margin of error is 3 points. This figure includes "leaners" but the Obama's margin is the same without them. The Fox poll put Obama's lead at 3 points, down from 9 the previous week.

The poll says that Obama had reached several "key thresholds": more than half say he is prepared for the job, nearly half believe in his ability to handle an international crisis, most expect him to be able to reach across the aisle and work with Republicans and most say he understands and cares about them. Obama has also benefited from a surge in early voting.

Another big factor is that 59 percent of voters now say that Sarah Palin is not prepared to be Vice President compared to 35 percent who say she is. That is a 16 point swing to the negative since the beginning of the month.

Voters who have seen some of the television commercials from both presidential candidates overwhelming say that John McCain's campaign mostly used its ads to attack Barack Obama while Obama's campaign ads mostly talked about what he stood for, according to a New York Times/CBS News poll conducted Oct. 25-29.

Nine out of 10 registered voters have seen at least some ads and they said, by a 64 percent to 20 percent margin, that they were mainly attacks on Obama. Half the voters said Obama's ad explained his positions while only 30 percent were used to attack McCain. A plurality of Republicans, 45 percent, said most of McCain's ads were negative but 48 percent of them pinned that label on Obama as well.

Sixty-four percent of independent voters viewed McCain's ads as negative while 48 percent said Obama's were positive.

John McCain has narrowed Barack Obama's lead with just days to go before Election Day, with Obama now ahead by 47 percent to 44 percent among likely voters with 2 percent preferring "other" and 6 percent undecided in a Fox News/Opinion Dynamics poll conducted Oct. 28-29. The margin of error is 3 points. Obama had led by 9 points in The Fox poll conducted Oct. 20-21. Obama's margin is the same when measured for all registered voters.

Fox says, "The race has tightened in part because of changes in a couple of important swing voting groups. Independents back Obama by 5 percentage points today, down from a 9-point edge last week. Similarly, among white Catholics, Obama held an 11-point edge over McCain last week and today they split 46-46."

Here are our latest updates on Senate races around the country. The big news is in Alaska where a poll taken a day after Republican Sen. Ted Stevens was convicted on corruption charges showed Democratic challenger Mark Begich opened a significant lead, and most Alaskans said Stevens should resign.

There has been a lot of musings about polls recently ranging from the proliferation of them, what their impact is on the political process and speculation about how accurate they are, especially with the first black candidate for President in the race. So, we thought we'd give you a sampling:

New Republic: How Many Polls Does it Take to Screw Up an Election?

This new, frenetic age of polling has not necessarily led to more empirical certainty. The very instantaneousness of polls threatens to shape perceptions as much as record them. And the deluge of polling data has just given partisans another opportunity to cherry-pick facts and impugn their rivals. In this besieged environment, even pollsters themselves fight bitterly over the best way to measure public opinion and whether some of them have it exactly right--or very, very wrong.

Barack Obama is leading John McCain 52 percent to 36 percent among registered voters with 3 percent for Ralph Nader, 1 percent for Libertarian Bob Barr and 8 percent for other candidates or undecided, according to a Pew Research Center poll conducted Oct. 23-26. The margin of error is 3 points. Among likely voters, Obama's margin is 53 percent to 38 percent. Pew says this is the fourth straight survey in which the GOP ticket has been edging down.

The poll found several "ominous" signs for McCain: his support is declining across most demographic blocs with the exception of white evangelical Protestants, Obama is running nearly even with him in "red" states that George Bush won in 2004, and Obama holds a 19 point lead among the 15 percent of voters who have already cast a ballot.

Obama also leads when it comes to how "strong" the level of support is among his backers, with 74 percent falling into that category compared to 56 percent for McCain.

Of the 8 percent of voters who are undecided, 29 percent say they might vote either was, 7 percent lean towards Obama, 7 percent lean towards McCain, 8 percent lean towards neither and 49 percent "don't know."

Americans believe by 71 percent to 23 percent that Barack Obama will be elected President next week and that includes a 49 percent to 46 percent plurality of John McCain's supporters, according to a Gallup poll conducted Oct. 23-26.

A poll of nearly 25,000 students attending more than 800 colleges in four battleground states finds overwhelming majorities of those registered to vote favoring Barack Obama, according to CBS News, UWIRE and the Chronicle of Higher Education. UWIRE is a news service run by college journalists. The survey was conducted Oct. 6- Oct.19.

Students favored Obama 67 percent to 29 percent in Pennsylvania, 61 percent to 35 percent in Ohio, 62 percent to 34 percent in North Carolina and 66 percent to 29 percent in Colorado. Those enthusiastically supporting Obama number between 51 percent and 61 percent in the four states while those that enthusiastic about McCain number between 29 percent and 34 percent. The percentage of students who say they will dfineitely vote ranges from 82 percent to 91 percent.

As the campaign for President winds down with Barack Obama consistently ahead in the polls, Gallup notes that there have been only 2 instances in 14 elections dating back to 1952 when the candidate ahead in its polling at this point did not go on to win.

One example was the contest between Jimmy Carter and Ronald Reagan in 1980 where Reagan had been trailing by 8 points, and then turned that around when he betsedCarter during a late-in-the-campaign debate on Oct. 28 (at least, in enough voters' minds), moved into a 3 point lead in the next poll and won the election by 10 points. Not an option available to John McCain.

The other example is the 2000 campaign where George Bush had been leading for most of the last month but Al Gore came back to eke out a 48.4 percent to 47.9 percent victory in the popular vote. But we know how that turned out.

Hubert Humphrey almost did this in 1968 when Richard Nixon's 8 point lead in September shrunk to 1 point just before the election, and the final outcome was decided by less than a percentage point.

Gallup has a neat chart of all the 14 races on its site.

Barack Obama is leading John McCain 53 percent to 40 percent with 1 percent preferring some other candidate and 6 percent undecided. in a Newsweek poll conducted Oct. 22-23. The margin of error for all adults is 3.6 percent for registered voters. Obama had led by 11 earlier this month and was tied with McCain in Newsweek's Sept. 10-11 poll. Obama's favorable to unfavorable ratio is 62 percent to 32 percent while McCain's is 50 percent to 44 percent.

The biggest demographic and party identification gaps are Obama's 8 point lead among independents, his 13 point lead among women, his 63 point lead among non-whites, and double-digit leads among voters under 64. McCain's biggest advantage is his 65 percent to 29 percent lead among white evangelicals.

If voters could cast ballots separately for Vice President, Joseph Biden would beat Sarah Palin 54 percent to 37 percent. She is viewed unfavorably by 46 percent of voters and favorably by 44 percent. Twenty-two percent of voters said the choice of Palin as running mate made them "a lot less likely to vote for McCain." They said by 55 percent to 40 percent that she was not qualified to step in as President. Voters say by 57 percent to 35 percent that Palin is not well-informed on foreign policy. And while 70 percent find her personally likeable, voters say by 47 percent to 39 percent that she has mostly made unfair personal attacks on her opponents on the campaign trail. As far as the now-famous $150,000 shopping foray Palin made with the help of RNC money, 68 percent said it did not affect their image of her as a reformer with small town values while 27 percent said it did.

Barack Obama is leading John McCain 52 percent to 41 percent with 2 percent for Ralph Nader and 1 percent for Libertarian Bob Barr in a poll of 15 battleground states conducted Oct. 19-21 for National Public Radio. The margin of error is 3.2 points.

Obama leads by 12 points among independents.

"The race has broken open," said Democratic pollster Stan Greenberg who conducted the survey with Republican Glen Bolger. "Some big things have happened that have closed off the campaign that McCain could have run. He's lost independents, now losing them by 12 points. He was the one Republican this year who could have won Independents, and now he's losing them by double digits."

Barack Obama is leading John McCain among likely voters by 52 percent to 39 percent with 5 percent undecided in a New York Times/CBS News poll conducted Oct. 19-22. The margin of error is 3 points. A round-up of the other major national polls, for comparison purposes, is at the bottom of this post. By more than 3-to-1, voters expect Obama to win regardless of who they support.

Voters believe Obama has the temperament and personality to be President by 75 percent to 19 percent, a 10 point gain since mid-October. They say by a 50 percent to 45 percent margin that McCain has those qualities, a 6 point drop for him. Voters are comfortable with Obama by a 62 percent to 34 percent margin compared to 49 percent who are uneasy with McCain and 47 percent who are comfortable with him.

Earlier in the campaign, there were questions about whether Barack Obama could win over the Jewish vote which has been an important part of the Democratic base. Gallup says based on monthly averages of its daily tracking polls that Jewish voters appear increasingly comfortable with his candidacy. In June, he led John McCain among Jewish voters by 62 percent to 31 percent, numbers that have now risen to 74 percent to 22 percent.

There were two big releases of polls today focusing on key states. The Big Ten Battle Ground Poll showed Barack Obama with significant leads over John McCain in eight Midwest states. A Quinnipiac University Swing State Poll showed Obama riding a surge of support based on the belief he would better handle the economy. Quinnipiac said, "With 12 days to go, Sen. McCain is narrowing the gap in Florida, but fading in Ohio and barely denting Sen. Obama's double-digit lead in Pennsylvania."

Also interesting to note that a new poll has Obama moving ahead in Montana, which went Republican in each of the last five elections except in 1992 when Ross Perot's independent candidacy siphoned off votes from the first President Bush. CQ Politics is changing its rating of Montana from "Leans Republican" to "No Clear Favorite." We are also moving Indiana from "Leans Republican" to "No Clear Favorite," Ohio from "No Clear Favorite" back to "Leans Democratic," and North Dakota from "Leans Republican" to "No Clear Favorite."

A new Pew Research Center survey conducted Oct. 16-19 has painted a picture of what kind of role the Internet is playing in this year's campaign.

Fifty-nine percent of voters say they have sought out some kind of election content on the web or have engaged in some kind of online communication about the campaign. While some of the comparisons between use of the Internet now and last December are no doubt skewed by the fact that we're actually in the thick of the election battle, there were big jumps in the numbers of voters watching political videos (from 24 percent to 39 percent), e-mailing about politics (18 percent to 37 percent) and visiting candidate websites (16 percent to 23 percent).

Liberal Democrats have donated money to the campaigns of their choice in greater number than their GOP conservative counterparts, according to a survey by the Pew Research Center conducted Oct. 16-19. Thirty-four percent of liberals said they had given money to any of the presidential candidates during the course of the campaign compared to 13 percent for conservatives. Overall, 19 percent of Democrats say they have donated money compared to 13 percent of all Republicans.

In contrast to most of the other major national surveys this week, an Associated Press-GfK poll has Barack Obama and John McCain statistically tied at 44 percent to 43 percent among likely voters. The margin of error is 3.5 percent. The poll was conducted Oct. 17-20. Obama had a 7 point lead in AP-GfK's previous poll.

(A rundown of the other polls, all of which had Obama ahead by 8 points or more, is at the bottom of this post).

The poll said "the race narrowed after the third debate as GOP-leaning voters drifted home to their party and McCain's 'Joe the plumber' analogy struck a chord." Even that contrasted with others polls that said the "Joe the Plumber" tack had not resonated with voters.

Obama is leading McCain 49 percent to 40 percent among likely voters with two percent preferring someone else and 8 percent undecided in a Fox News/Opinion Dynamics poll conducted Oct. 20-21. The margin of error is 3 points.

Other major national polls this week:

• Ipsos/McClatchy: Obama 50, McCain 42.
• Wall Street Journal/NBC News: Obama 53, McCain 42.
• Pew Research Center: Obama 52, McCain 38.
• New York Times/CBS News: Obama 54, McCain 43.

Polls from the Washington Post/ABC News, Harvard University's Institute of Politics and Gallup underline Barack Obama's strength among younger voters.

The Post/ABC poll says Obama leads McCain by 12 points among white voters under 30, a group that John Kerry lost by 10 points in 2004.

The Harvard poll, conducted Sept. 12 - Oct. 6, says voters in the 18-to-24 group favor Obama by 56 percent to 30 percent with 15 percent undecided. Forty percent of these voters said McCain's choice of Sarah Palin as running mate made it less likely that they would vote for the ticket compared to 19 percent for Joseph Biden. Sixty percent said the choice of Biden made no difference to their decision while only 35 percent said that of Palin.

Barack Obama is leading John McCain 50 percent to 42 percent among likely voters with 1 percent for Ralph Nader and 7 percent undecided in an Ipsos/McClatchy poll conducted Oct. 16-20. The margin of error is 3.5 percent.

As yesterday's Wall Street Journal/NBC News poll showed, the poll says "Obama's gained ground among voters across the board, even on issues where McCain still has an advantage and on some where the Republican usually would expect to be ahead." Obama leads McCain by 8 points on one of the favorite Republican themes - family values.

Voters favor Obama on handling jobs and the economy by 16 points and health care by 24 points. They still give McCain a 12 point edge on national security issues but that's down from margins of more than 20 points that he had in early polls. In any event, voters put more importance on the economy than national security by a 3-to-1 margin.

Other major polls from this week:

• Wall Street Journal/NBC News: Obama 53, McCain 42.
• Pew Research Center: Obama 52, McCain 38.
• New York Times/CBS News: Obama 54, McCain 43.

Thirty-nine percent of McCain supporters said they would vote for him because he was the lesser of two evils. In another stark contrast, 46 percent of McCain supporters said their vote was more for McCain than against Obama while 67 percent of Obama supporters said their support was more for their candidate than against McCain. Twenty-seven percent of McCain supporters said they were motivated mainly by rejecting Obama while only 8 percent of Obama supporters said they had made their choice principally because of opposition to McCain.

Barack Obama is widening his lead over John McCain, now running ahead of him 52 percent to 38 percent among registered voters with 10 percent undecided in a Pew Research Center poll conducted Oct. 16-19. The margin of error is 2 points. That's a 4 point gain from Pew's poll conducted Oct. 9-12. Obama's margin when only likely voters are included is 53 percent to 39 percent.

Pew says a "widespread loss of confidence in McCain appears to be the most significant factor in the race." Forty-one percent of voters see McCain as "having poor judgment" compared to 29 percent for Obama. Thirty-four percent say he is too old to be President, up 11 points from mid-September. Voters view Obama as the more inspiring candidate by 71 percent to 37 percent.

Obama leads McCain by 21 points when voters are asked who can best handle the economy, a gain of 12 points since mid-September. He now leads 48 percent to 42 percent on who can best handle Iraq, after trailing McCain on this issue by 7 points.

Barack Obama's favorability ratings have gone up from where he was before the first presidential debate while John McCain's have gone in the opposite direction, according to a New York Times/CBS News poll conducted Sept. 21-24 and again Oct. 17-19.

Obama's favorable to unfavorable ratio was 43 percent to 26 percent with 25 percent undecided in the first sampling and now stands at 53 percent to 33 percent with 13 percent undecided. McCain's ratio was 36 percent to 35 percent with 25 percent undecided in September but now he is seen unfavorably by 45 percent and favorably by 36 percent with 16 percent undecided.

Twenty-one percent of voters said their opinion of Obama had changed for the better in the last two weeks compared to 14 percent who said it changed for the worse and most attributed their more positive view to his debate performance. Twenty-three percent said their opinion of McCain had changed for the worse compared to 12 percent who said it had improved, and most of those who said it had changed for the worse blamed his attacks on Obama.

Overall, if "leaners" are counted, Obama is leading McCain 54 percent to 43 percent compared to the 6 point margin he had in September.

John McCain has cut some of the gap between himself and Barack Obama on who Americans think better understands the nation's economic problems, but Obama still leads 53 percent to 44 percent with 1 percent either preferring someone else or no one at all, and 2 percent with no opinion in a Washington Post/ABC News poll conducted Oct. 16-19. The margin of error is 2.5 percent. Obama had led McCain by 31 points on the economy issue last week, but the poll says McCain's efforts to focus on the economy at the debate and on the campaign trail have cut that to 19 points.

McCain's "I am not President Bush" retort to Obama at the debate helped push down somewhat the number of voters who think McCain would likely continue the policies of President Bush. Last week, they held that view by 52 percent to 45 percent, and the new poll says voters now believe it by 49 percent to 48 percent.

The McCain campaign and Republicans have sought to tie Barack Obama to what they see, and what voters to see, as some unseemly associations - the community organizing group Acorn which they accuse of voter registration fraud, and the '60s-era radical William Ayers. "We need to know the full extent of that relationship," McCain said during the final debate.

But a Washington Post/ABC News poll conducted Oct. 16-18 says voters, by a 60 percent to 37 percent margin, do not believe the Ayers connection is a legitimate issue. Their judgment is closer when it comes to Acorn with voters saying by 49 percent to percent the Obama campaign's association with ACORN is a legitimate issue.
