My very conservative Christian sister-in-law just emailed me and asked me why I wouldn't vote for Santorum. What can I tell her about Santorum that will turn her off to voting for him?

I'll say she's asking me because she values my opinion. She knows I have libertarian views and doesn't agree with all of them, but she has a hard time staying informed about the GOP candidates so she turns to me for advice. Of course, I shill for Ron Paul every chance I get and I've been able to de-rail her off of Gingrich, Perry and Bachmann for their hypocritical Christian bullshit....I'm just don't know enough about Santorum to say what makes him a "No-go" for Christian conservatives like her. Any skeletons in Rick's closet I can throw her way?
