She should and she was making great points on the mandate, but then she threw unfounded allegations at Perry, it looked petty to me - she was already winning that argument. But she should have gone after Romney for RomneyCare which is basically obamacare.
We simply cannot have Romney as the nominee. And, I agree that the candidates should be swinging away at the RomneyCare matter. It seems they are all vying for some potential cabinet position or something....weird.
