AP isn't reporting any vote totals since the polls are still open, but there is this:
An exit poll finds one in 10 voters in Pennsylvania's Democratic primary changed parties since the start of the year so they could vote in the hotly contested election, which is open only to registered Democrats.[...]
Early exist polls found many who voted in the Democratic primary had switched from another affiliation.
The survey Tuesday for The Associated Press and television networks indicates about half of the party-switchers formerly were registered Republicans and the rest had been unaffiliated with either party.
The exit poll finds about one in five voters made their voting decision within the final week of the six-week Pennsylvania campaign. Half said campaign ads were important to their vote.
At least four in 10 voters said the country is in a serious recession and at least as many called it a moderate recession.
Late deciders in other primaries have largely broken for Clinton, and the final Pennsylvania opinion polls shows as high as 10-11% percent undecided in Pennsylvania.
The exit polls show a smaller percentage of late deciders -- 23% -- than in previous states. The economy mattered most to 54% of voters. (TV news reports say that Clinton won these folks.)
The change versus experience question has been settled: 49% said change was their top vote-generating quality, versus 26 percent who said experience was.
About 15% of the electorate was made up of new voters. 37% are gun owners.
Still petulant: more than 60% of Clinton voters say they wouldn't be happy if Obama were the nominee; about half of Obama voters say the same. 25% of Clinton supporters say they'd vote for McCain in the general election; 17% of Obama supporters say they'd vote for McCain in the general election.
Still, 57% of Pennsylvanians believed that Sen. Clinton "attacked" unfairly compared to 49% who thought Obama did.
UPDATE II: The New York Times is reporting high voter turnout:
Pennsylvania is on its way to the record turnout that election officials have been predicting for weeks, according to poll workers from across the state.
Election officials were reporting extremely heavy voter activity in many of the state's 67 counties throughout the morning, starting with long lines reported even before the polls opened at 7 a.m.[...]
In Beaver County, in the western portion of the state, turnout appeared even higher than the county officials had anticipated.
"We're just overwhelmed," said Geri Shuits, a polling clerk in Beaver County. "I've gotten so many phone calls, I just can't keep up."
At one polling station, the number of voters they've had was already as high as by the end of the night last year, she added, referring to the November 2007 municipal election.
In Philadelphia, turnout is reportedly "very heavy," said Abe Amoros, the executive director of the state Democratic Party. In the counties surrounding Philadelphia, including Bucks, Delaware, Montgomery and Chester, most polling stations have reported long lines.
The Democratic primary election in 2004 saw a 26 percent turnout, but this year promises to be much higher, Mr. Amoros said.
"We're predicting at least double the turnout of 2004," he said. "This is the first time we've been major players in the presidential primary since 1976."
UPDATE III: From CNN (TV) via TalkLeft:
- 37% said they have a gun. 58% of them voted for Hillary
- 39% attend church weekly. 59% voted for Clinton.
