I've been reading some numbers at both CNN and Foxnews that indicate that 51% of people polled thought Obama won the debate - while 38% thought McCain won. Both reports indicate that there were more democrats surveyed than republicans.
For those that claimed they weren't committed to either candidate, 39% thought Obama won the campaign while 24% thought the win went to McCain - the rest were tied.
Personally I thought it was a draw - even though I thought McCain did "ramble" a bit in parts - the path he got to repeating hims comments about looking in Putin's eyes was pretty circuitous. I'd give Obama the nod though since he held his own against someone with more experience.
