And Obama will destroy him on them along with the fact that by debate time, people will be disgusted with the guy. As EG/Fred said, he's not geniune, and he's going to come off very unlikable and IMO, will not win any debates, and probably lose most of them.
Hillary is extremely intelligent and comes off as a very genuine person, more so than Obama. Romney isn't going to be close to her level in 2008.
I haven't seen Paul debate but I'm sure he'll do just fine against Biden, which nobody will give a fuck about anyways. And yeah, I agree that presidential debates don't matter a whole lot and Romney will probably be pretty far down in the polls by the time they come along.
