The fact that he ever won in PA is amazing. Nobody should be surprised that he got trounced in 2006.
Bob Casey, Jr. was the progeny of a very well-loved politician, and 2006 was a disaster for the GOP.
Also, Santorum had a reputation for being very conservative. I think liberal PA became tired of it.
Santorum has been a much more reliable conservative than Newt Gingrich. He’s stuck to his guns over the years despite the abhorrent treatment he has received from the liberal media for his view on gay marriage and abortion. In fact, the sodomites use his name to describe something as disgusting as can be imagined.
He has been a stalwart defender of the unborn, most notably in his debate with Barbara Boxer in 1998. He authored the Partial Birth Abortion Act.
He is not the ideal choice, but he is a lot better than Mitt Romney. And he would be able to win a lot of blue collar voters in states like OH, PA, and MI.
Personally, I think half the people who voted for Jr thought he was his dad...
