Romney has been doing practice debates, at least since he got the nomination. Obama has been fundraising, attending parties, going on talk shows, probably a few rounds of golf.
It’s likely he trusts his self-perceived god given talent for rhetoric to pull him through.
Obumbler damn near flunked out of Occidental and had a communist shoehorn transfer him to Columbia and again into Harvard Law where not one article was written by him and not one grade has been released. He is a disbarred lawyer who surrendered his law license and taught part time till he hacked his way into politics. He has never been known as a hard worker. I bet he has done NO debate prep.
Obama will have a wire in his ear with someone telling him what to say. You gotta know he will already know what he will be asked——or he will tell them what they MAY ask.
