UNDATED (AP) -- New Quinnipiac University polls suggest Sarah Palin has been good for John McCain's campaign in three key swing states, though Barack Obama has actually taken a lead in one of them.
Obama and McCain were about even in Ohio last month, but Obama now leads 49 to 44 percent. McCain has gained support from backers of Hillary Rodham Cliton and white women, but Obama still has a 10-point advantage with women overall.
Florida looks better for McCain. His lead over Obama in Florida has expanded. He's up 50 to 43 percent, and almost a quarter of Clinton's supporters say they back McCain. Last month only 14 percent said that.
McCain is also closing the gap in Pennsylvania. Obama still leads 48 to 45 percent. But he was up 49-42 last month and is losing ground with independents.
(The Florida and Pennsylvania polls have a margin of sampling error of plus or minus 3.1 percentage points, while in the Ohio poll the margin is 2.7 percent. The telephone surveys of likely voters were conducted from September 5th to the 9th.)
