I've already written that I think Mitt Romney won on the issue of a Line Item Veto.
However, as Dean noted, his answer on the question of Congressional authorization was very, very lame:
CHRIS MATTHEWS: “Governor Romney, that raises the question, if you were president of the United States, would you need to go to Congress to get authorization to take military action against Iran's nuclear facilities?”
ROMNEY: “You sit down with your attorneys and tell you want you have to do, but obviously the president of the United States has to do what's in the best interest of the United States to protect us against a potential threat. The president did that as he was planning on moving into Iraq and received the authorization of Congress...”
MATTHEWS: “Did he need it?”
ROMNEY: “You know, we're going to let the lawyers sort out what he needed to do and what he didn't need to do. But, certainly, what you want to do is to have the agreement of all the people -- leadership of our government as well as our friends around the world where those circumstances are available.”
