Headline is a little deceiving...he had the same lead a couple days in a row. His post convention bounce got stuck at 8 points. Yes he expanded it from pre-convention, but then most conventions do that no matter who the candidate.
Yep, I thought that it would go up a little more from an 8 point lead, but it just stalled.
Obama went from having 45% of the vote in polls pre-convention to 49% post-convention -- not good news for him.
