A CBS poll of uncommitted voters who watched the debate appears at first glance to be more comforting to Kerry than the Gallup poll discussed by Rocket Man below. Both polls reflect the view that Kerry debated better, but the CBS report suggests that Kerry did better than Bush on key "internals" as well. However, at the end of the story we learn that, after the debate, Kerry’s support among CBS's "uncommitted" voters rose to 38 percent from 31 percent, and Bush’s to 31 percent from 19 percent. So Bush actually narrowed the gap among the surveyed "uncommitteds," and the CBS study group was tilted towards Kerry from the start.

Thanks to reader Mike D for pointing me to this poll.
