My initial winners and losers after watching the entire debate.

Winners:
Giuliani - Appeared confident and on the offense. Cleary acts like the front-runner.
Thompson - Shaky start, but finished very strong. Hurdled whatever bar was set for him.

Push/Draw:
Romney - Great first answer, but narrowly lost the dust-up with Giuliani over taxes, allowed Paul to hit him pretty good on his need to consult the attorneys and then got hit by Thompson at the end with Fred's "and to think I thought I was going to be the best actor on the stage." Romney sounded good, but did not help himself.
Huckabee - Wasn't his best debate, but continues to carve out his niche as the compassionate social conservative in the race.

Losers:
McCain - Looked old, did nothing to change the impression he is more second tier than first
