The debate reminded me a bit of the 1960 Nixon v Kennedy television debate.
In terms of presentation Romney definitely came out on top, he made sure to smile in all the right places (kennedy), and well practiced delivery and consistently stayed on message with his talking points. While Obama gave more substance and indepth responses (Nixon), but less "punchy" delivery. If content was the only thing that mattered than Obama would have won, but alas that is not the case in the age of 24 hour media cycles.
I'm expecting an aggressive Joe Biden at the forthcomming VP debate (he really held himself back in the previous election's debates against Palin as to avoid the "battering women" image), he's got ground to make up. And i'd think Obama will focus more on attacks during the next debate as well.
