This could happen if the conservatives in Pa. don't go all out to save Rick.
Way too many conservatives are going to do their best to make sure Santorum loses even though it means electing a liberal Democrat.
I think eventually Santorum will pull this out. One thing, Casey is anti-abortion and anti-gay rights although he is liberal everywhere else. The last time Santorum was up for re-election back in 2000, the Democrats nominated a pro-life, pro-gun Democrat in Ron Klink, and the national Democratic party barely helped him, and Santorum won re-election. Second, Santorum is a much better campaigner than people give him credit for. WHen he was in Congress, he represented a majority Democratic district. THird, Casey is only running on his father's name and he is not a great campaigner like Santorum. Once it plays out, it is likely Santorum will win re-election. Don't give up.
