Today we update Pennsylvania, California, New Hampshire, Wisconsin, Ohio, Nevada and Minnesota in our round-up of general election match-ups between John McCain and Barack Obama. As with the latest national polls, the movement in these polls and the ones we posted yesterday appears to be mostly towards Obama. A Time/CNN/Opinion Research poll said McCain was struggling in states that President Bush won in 2004 such as North Carolina, Ohio, and Indiana.

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 Florida, Ohio, Pennsylvania, Tennessee, Texas, Mississippi, Minnesota, Missouri, Nevada, Virginia and Oklahoma in our round-up of state-by-state general election match-ups between Barack Obama and John McCain. One set of the new polls is Quinnipiac University's swing state surveys of Florida, Ohio and Pennsylvania which like the AP-GfK and Pew Research Center surveys we posted earlier show Obama benefiting from the first presidential debate, greater voter trust in him on the economy and falling favorability ratings of Sarah Palin.

Obama also gained significant ground in polls conducted in five battleground states in a CNN/Time Magazine/Opinion Research poll released today. CNN polling director Keating Holland said, "Obama has gained ground among moderates in all five states." He added, That may have something to do with the first presidential debate. Some commentators knocked Obama for agreeing with McCain as often as he did, but moderates tend to like it when candidates appear willing to see the other side's point of view." The states were Florida, Minnesota, Missouri, Nevada and Virginia.

Today we update New Hampshire, Iowa, Michigan, Colorado, Pennsylvania, West Virginia, Montana, Florida and Hawaii 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."

• 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.
