Polls just closed across Pennsylvania. Cable networks have declined to call the race based on exit polling, declaring it "very close." Probably not the result Clinton was hoping for - at least right away.

Just-released exit polls posted on MSNBC.com showed Clinton winning among women, whites, union members, senior citizens, late deciders, gun owners, frequent churchgoers and voters earning less than $50,000 a year. They showed Obama winning among men, voters with college degrees, those younger than 45 and newcomers to the Democratic Party. He continued his dominance among African Americans, winning their votes 9 to 1.

Obama struggled with blue-collar, white male voters - a group Clinton courted with aggressive attacks on Obama's "bitter" comments and with surrogates including her husband, former President Bill Clinton, and Pennsylvania Gov. Ed Rendell. Clinton won nearly two in three of those voters, exit polls suggested.

The polls showed voters prized "change" over "experience," that they overwhelmingly believe America is in recession and that the economy weighs heaviest on their minds as an electoral issue. Two in three voters said Clinton attacked Obama unfairly.
