We've updated Ohio, Colorado, Michigan, Minnesota, Wisconsin, Arkansas, Massachusetts, Oregon, Pennsylvania, Vermont, North Carolina, Kansas, Kentucky, California and Florida in our round-up of state-by-state general election match-ups between Barack Obama and John McCain. We are also putting three states into different categories. Indiana and North Carolina move from "Republican Favored" to "Leans Republican." And Poll Tracker sheepishly admits it got out of synch with our race ratings team, and is moving Pennsylvania from "Democrat Favored" to "Leans Democratic."

Today we update Ohio ("No Clear Favorite"), Michigan ("Leans Democrat"), New Hampshire ("No Clear Favorite"), New Mexico ("No Clear Favorite"), Pennsylvania ("Democrat Favored"), Virginia ("Leans Republican"), Florida ("No Clear Favorite"), Minnesota ("Leans Democratic"), North Carolina ("Leans Republican"), Georgia ("Republican Favored"), New Jersey ("Safe Democrat"), South Dakota ("Safe Republican") and Wisconsin ("Leans Democrat") in our round-up of state-by-state general election match-ups between Barack Obama and John McCain.

Here's a summary of our race ratings categories. Use this link for background on how we arrive at them

• No Clear Favorite, for races that are deemed to close to call.
• Leans Democratic and Leans Republican, for highly competitive races in which the named party is perceived to have at least a slight edge, but in which an upset is a highly plausible possibility.
• Democrat Favored and Republican Favored, for races in which the named party has a clearer advantage and is likely to win, though an upset cannot be completely ruled out.
• Safe Democratic and Safe Republican, for races in which the named party is viewed as certain to win.

Today we update Ohio (the ninth poll of the state so far this week), Michigan (where two new polls show Barack Obama and John McCain in a statistical tie), North Carolina (where the latest poll shows the race as a tie), Missouri (statistically tied) and Illinois, South Carolina, Maine, Connecticut and Tennessee.

We've decided to do a little redecorating on our page of state-by-state match-ups between Obama and McCain by grouping states according to which CQ Politics race rating category they fall. You'll see some instances where you may wonder why we gave a particular rating to a state, when the polls don't seem to clearly indicate the same outcome. The answer is that polls are only one factor we take into account when we rate a race. For a fuller explanation, read the column by our Rajah of Ratings, Bob Benenson, who discusses all the elements that go into our decisions.

Our latest round-up of match-ups between Barack Obama and John McCain updates 33 states, largely because of an outpouring of polls from American Research Group, and a bunch more from CNN/Time/Opinion Research and Rasmussen Reports. Also, check out CQ Politics' election forecasts for detailed stories on races in each state from the tops of the tickets down.

• Florida: Obama and McCain are tied at 48 percent each among registered voters in a CNN/Time/Opinion Research poll conducted Sept. 14-16. The margin of error is 3.5 percent. A Fox News/Rasmussen Reports survey conducted Sept. 14 had McCain leading Obama 49 percent to 44 percent with 2 percent each for Ralph Nader and Libertarian Bob Barr and 3 percent undecided in. The margin of error was 4.5 percent. The two were tied in its last survey. McCain had stronger support among his party than Obama did among Democrats: 86 percent to 70 percent with 21 percent of Democrats saying they will vote for McCain. McCain also upped his lead over Obama by 2 points to 50 percent to 45 percent with 5 percent undecided in a Public Policy Polling survey conducted Sept. 6-7. The margin of error was 3.1 percent. Obama's problem appeared to be that as white voters move out of the undecided camp, they were mostly headed for McCain. Obama was staying close because of his 7 point lead among Hispanic voters (13 percent of the sample) and 78 point lead among blacks (16 percent of the sample). Republicans have carried the state in four of the last five elections including, of course, the hotly-contested outcome in 2000 where the state was awarded to George Bush by a hair. CQ Politics' Election Forecast has "No Clear Favorite here.

Today we update New Jersey, North Carolina, Maine and Mississippi in our state round-up of Senate race polls. Also, check out our state-by-state election forecasts for detailed stories on races in each state from the tops of the tickets down.

• New Jersey: Democrat Frank Lautenberg leads former Republican Rep. Dick Zimmer 51 percent to 40 percent with 1 percent choosing "other" and 8 percent undecided among likely voters sampled in a Marist Poll conducted Sept. 5-8. The margin of error is 3.5 percent. A Quinnipiac University conducted Aug. 4-10 had Lautenberg ahead by a closer 48 percent to 41 percent margin with 11 percent undecided in a survey of likely voters by. The margin of error is 2.6 percent. Although the lead doesn't look insurmountable, Quinnipiac's Clay Richards said, "It's summer and voters aren't paying a lot of attention to this race. When they do, the incumbent's lead may get bigger - if voters don't get too concerned about the Senator's age." Those polled believed that Lautenberg was too old to serve another 6 years by a 55 percent to 39 percent margin, and that even included 50 percent of Democrats. But that doesn't appear to be helping Zimmer whose own problem is that 62 percent of voters don't know enough about him to form an opinion. A Rasmussen Reports poll conducted Aug. 4 had Lautenberg ahead 51 percent to 33 percent. That was up from his 13 point lead last month. Lautenberg leads 45 percent to 28 percent among unaffiliated voters and by 60 percent to 25 percent among women, while Zimmer leads 43 percent to 40 percent among men. Lautenberg's favorable-to-unfavorable numbers are 48 percent to 45 percent and Zimmer's are 37 percent to 41 percent. A Strategic Vision poll conducted July 11-13 had Lautenberg ahead 48 percent to 32 percent with 20 percent undecided. CQ Politics rates this race "Democrat Favored."
