Santorum does in fact have, shall we say, fraught relationships with several different groups in our society, so The Globalizer is right in that it doesn't, perhaps, require a tremendous leap of logic, but it's still unfair, because from what I know of Santorum this really doesn't include racism. I can believe that he got tongue-tied at basically the worst conceivable moment, but it's still somewhat problematic that he's capable of being opened up to this kind of question being asked.
If you want to go by that logic, anyone with an R after their name can routinely be accused of racism and people will automatically believe it.And that's why 95% of blacks vote Democrat!
