Voters just don't like Santorum

Rick Santorum has spent 12 years in the Senate -- and millions of dollars on TV ads for a third term. Yet a lot of Pennsylvania voters just plain don't like him.

Polls show Santorum's approval rating is in the 30s, just about what it was a year ago. Roughly the same number of voters view him unfavorably as favorably.

Questions over the use of Pennsylvania tax dollars to pay for the cyber schooling of his six children in Virginia continue to dog him. Anger lingers over comments he made in a book last year criticizing some working parents, as well as statements he made in opposition to same-sex marriage and in support of keeping Terri Schiavo alive.

"Santorum's real problem is Santorum," said Clay Richards, a Quinnipiac University pollster.
