Poll porn from Florida, Pennsylvania and Ohio shows Obama holding his leads and that McCain's latest stunt (go for broke in Pennsylvania) is likely to go as well as the rest of his stunts:

Quinnipiac:

FLORIDA: Obama 49 - McCain 44; OHIO: Obama 52 - McCain 38; PENNSYLVANIA: Obama 53 - McCain 40

Pennsylvania

Obama leads 59 - 35 percent with women, while men split with 47 percent for Obama and 45 percent for McCain. White voters back Obama 49 - 44 percent, while black voters back him 92 - 3 percent. Independent voters back the Democrat 55 - 35 percent. Obama gets a 60 - 30 percent favorability, compared to McCain's 51 - 41 percent. Palin's favorability is a negative 38 - 43 percent, with Biden at 54 - 22 percent.

The economy is the most important issue, 55 percent of Pennsylvania voters say, and voters trust Obama more than McCain 54 - 36 percent to handle this issue, compared to 55 - 36 percent October 1.

By a 47 - 45 percent margin, voters trust McCain more to handle foreign policy, compared to 48 - 45 percent.

"Sen. Obama leads comfortably in Pennsylvania, mostly because he has pulled ahead in the four key suburban counties surrounding Philadelphia where Keystone State races are decided," said Clay F. Richards, assistant director of the Quinnipiac University Polling Institute.

"Obama is leading among whites and blue collar workers, but white men and 15 percent of Sen. Hillary Clinton's primary supporters are clinging to Sen. McCain, probably not enough to change the tide in the closing days of the campaign," Richards added.
