Right before the debate started Brit Hume said Barack had been working to shorten up his answers. I jokingly said to my wife "if Obama removes all of the ums his answers will be very short". That part he managed to do pretty well.
Barrack UHbama had one major malfunction on his Uhs... that was when he was stating he had a bracelet too! He looked down at the bracelet "Sgt Uhhhhh.." That was a major gaffe on his part with the positioning of this UHHH.
