It looks like he did very well in this last debate. He won the ABC post debate poll, the MSNBC poll and the Drudge Report poll. I have also heard that he has spent only $600,000 of his $3 million raised so far.
He as accomplished quite a lot with nothing but a strong message and little money. If he had a 90% household name recognition like guliani and mccain instead of <10% he'd probably be in first place for the nomination.
Here's a great clip from the recent debate
Love how romney tries to pull the "..but.....but..but 9/11" and gets shut up. Paul makes so many great points in that clip.
