It's not just somebody, it's the entire left bank..lol
You can correct me if I'm wrong after all the debates are finished but I thing the Big 'O' is letting Romney run with the line like a fish on the hook. I think that he's giving him enough rope just to hang himself with. Think if it like a prize fight and this is the first round bell. We'll see what the next two bring, but I think Obama is crazy like a fox and he's letting Romney run out the reel before he sets the hook and slams him on the deck.
