A word map (larger = more frequent) of the First Debate.

Looking at the actual word frequency is interesting. The number and uniqueness of words between the two candidates is nearly on par. McCain used “I” half again as much as Obama, “we” almost three times as often — but Obama was the only one to mention Bush.
Just looking above, Obama’s word choices of “going,” “make,” “now,” and “think” strike me as more powerful than “know,” “spending,” “got,” and “want” from McCain.
