Here’s audio of Sen. Jim DeMint (R., S.C.) making the case for Christine O’Donnell in Delaware.

I have a lot of respect for the senator, and take his talk about the futility of Republicans “having the numbers, but not the principles” very seriously. But what he has made the case for is backing really good conservative candidates in Republican primaries, even when they are underdogs up against moderates like Castle. I wish he had made the case for backing Christine O’Donnell.
