Pennsylvania exit polls

The WSJ's exit poll found that:

Sen. Obama's comments about bitter voters and their guns didn't do him any good with nearly four in 10 voters who own a gun or live with someone who does. They sided with Sen. Clinton by a sizeable majority.

Also interesting:

One in four Clinton supporters said they would vote for Sen. John McCain if Sen. Obama is the Democratic nominee. Sixteen percent of Obama backers said they would choose Sen. McCain over Sen. Clinton.
