I think Romney will do just fine up against Hillary. Just fine.
Yes, Mitt would do well against Hitlery talking about health care. Most of the current GOP field would.
What if the topic is abortion? Hitlery would say something like, "Well, I know where I stand, but as for Mr. Romney, it seems to depend on which office he's running for." What's Mitt's reply?
"Yes, Hilary I was wrong before. Now I see the light. Why do you still believe in butchering babies?"
