I'd say I feel the same way about Ron Paul - he brings a refreshing perspective to politics, but he's certainly not right on everything.

Santorum adds nothing to the debate but repetition of the narrative that's already going on. I should add to this that no one ever likes the same tactic they use to be used against them - in this case having Stallman define an extreme position to maintain a more pragmatic narrative.

All considered, I'm glad both Stallman and Paul are doing their thing - even if I don't agree with them much of the time.
