This poll seems to be "THE ONE" that matters to everyone. An interestping point here
SPECIAL NOTE OF CAUTION #2: The sample of debate-watchers in this poll were 31% Democratic and 33% Republican. That indicates that the sample of debate watchers is about eight points more Republican than an average CNN poll of all Americans, so the respondents were more Republican than the general public.
HUH!! If it's 31% Democrats and 33% Republicans, from where does this "eight points" oversampling come, other than the fact that fewer republicans watch CNN overall (a mere 18% of viewers according to a 2009 Pew poll)?
