Did Kerry get a post-convention bounce?
Well, it depends who you ask.
According to Gallup/CNN/USAToday's survey of likely voters, Kerry was ahead of Bush by 1 percentage point before the convention, but behind by 4-6 points after the convention. Ouch. But according to the WashingtonPost/ABC poll, Kerry was behind by 4 points before the convention, and ahead by 2 points after the convention.
In two other polls that were conducted just after the convention, and looked at registered voters (as opposed to likely voters), Kerry is now ahead by 4 points (American Research Group), or 5 points (CBS).
In any case, even by the Washington Post numbers, Kerry's bounce was among the smallest in recent history.
