PA elected Arlen Specter. Repeatedly. Liberals hate Santorum with a passion. There have been anti-Santorum signs and fliers here, printed up by some group that did the same type of thing against Bush in 2004. Santorum has national name recognition among libs. I'm not sure if it's his "It Takes a Family" book, or his remarks on gay marriage, or his Catholicism, or his... PA is basically half lib & half conservative. The libs own the two big cities, and Republicans own SOME suburbs (not Philly ones) and rural. Santorum is wonderful IMO, and Casey is a joke. They're not gonna vote FOR Casey though, just against Rick. It all boils down to anti-Values Voters.
Oh, yeah, the Santorums also homeschooled for awhile.
If Santorum is -12 to -16, Why are all the big name Dems showing up in PA stumping for Casey?
