As as to taking out those opposed to Romney, I think they have taken out or damaged themselves by their performance in debates (Perry) or performance in glibly answering complicated questions (Cain on foreign affairs). And BTW Cain is still doing quite well.
As to Romney, he is so dull and unlikeable...what's to attack?
I don't think it'll be Romney because Romney can only muster 20-25% support. And on top of that, everyone is sick and tired of being told who the nominee will be by "D.C. insiders."
Yeah, but it's steady. No one - not even the other Republican candidates - are really trying to take him out because of it.
The conservative candidates should gang up on him and move him out before it's too late. Rove Inc. has chosen him, so he's still going to be standing in the end, and that gives him unlimited funds, too.
