At today's press conference with Obama, CBS' Norah O'Donnell informed the president that Romney had called him "the most feckless president since Carter." Big time burn.

In response Obama smirked, "Good luck tonight," and moved on.

It is also important to note that Norah O'Donnell looks like a fox in that red dress. Get your quotes, lady!

Update: Mitt Romney responded to a reporter asking for comment on Obama's "well wishes" with the following:

Do you think that was an endorsement? I hope so, but I don't think so. I appreciate the good wishes, and wish him the best.
