On Fox News this morning, Mitt Romney took a pass at attacking Herman Cain.
KILMEADE: One thing was clear. When Governor Perry got in, he catapulted over you; you went after him.
Now Herman Cain is either tied with you or nipping at your heels. Where is Herman Cain vulnerable?
ROMNEY: Herman Cain's a good man, and I respect him. I'm not going to look at his vulnerabilities. I'm going to talk about the things I need to do.
As I said earlier, this shows that Romney doesn't really fear Cain (and, actually, probably likes the fact he takes votes from Cain).
Yesterday, Emily Schultheis put together a montage of clips where Romney praises Cain.
I can only find one example where Romney pseudo-attacked Cain in this race, and it's just because it fit into Mitt's broader message -- that he's the only guy in the race with both business and government experience.
"I think the only other person that has that kind of extensive private sector experience besides me in the Republican race is Herman Cain, and I respect Herman Cain, but I also think it's helpful to have that government experience that I've had."
