It might have something to do with supporting Specter over Toomey. I will say this race will tighten considerably. It should be exciting, it will be Santorum's toughest battle.
Bush couldn't beat an unpopular Kerry in 04 when Bush won the national vote by 2.5 percent and lose PA by 3 percent.
Now Santorum is going up against a popular candidate in Casey. Casey could take the next year off and still win. Casey will vote the liberal line in the senate too. Remember Harry Reid is pro life too. If I were on Santorum's staff I would be sending out resumes. Santorum shouldn't have even run he will only be humiliated and give the DU crowd something to cheer about. Santorum might even kick out Fitzpatrick. If Santorum wasn't in the race there would be a lot less dem turnout.
I forgot about that. Why do they do things like that when the people want someone besides an incumbent? I would probably not support him either since he helped give us Arlen Specter (how much did that help Republicans?!).
