Is Obama’s Bounce Gone?

Silver compares Gallup and Rasmussen polls – which show the bounce fading – to an NBC News/WSJ poll that gave Obama a five-point advantage:

These polls almost seem to inhabit different universes. As I’ll describe in a separate article, the methodological choices made by pollsters may have something to do with it; Mr. Obama’s bounce has been much more noticeable in polls that use live interviewers and that call cellphones. But it does not do any good to pretend there is a consensus in the polls when there isn’t. Sometimes there is simply no alternative to remaining patient until one emerges. The downward trend for Mr. Obama in the Gallup and Rasmussen trackers is closest thing we have to a theme in the polls for the time being.
