Apparentely when running against someone like Santorum, who the Democrat is is irrelevant, many people simply aren't going to vote for such a person, period.
Well.......DUH!
The Democrats could have run pretty much anybody against Santorum this year and beat him handily. Bottom line is that Santorum was just a very, very weak candidate. His negatives were simply too high. He would not have been able to beat even a third tier Democratic candidate in Pennsylvania this year.
This should be obviously, but many Republicans here still don't seem to buy that. The fact that Santorum is not a mainstream politician still seems lost to many even after his 18 point defeat.
Nominate anyone but Casey and I would have guarenteed that no one could have beaten him by more than ten points.
That isn't exactly saying much for the guy.
