UPDATE: Via Steve Benen, USA Today has Obama ahead 51%-39% while AP/Ipsos has him ahead by only 46%-43%. So it's all over the map. I guess there's no telling what's really going on.
LATEST POLLS....Since I posted about the latest Gallup tracking poll yesterday, I guess it's worth noting that the latest CBS/New York Times poll provides wildly different results. Gallup's national poll shows Obama and Clinton virtually tied (Obama is ahead 47%-45%), while the NYT poll gives Obama a huge lead, 54%-38%. I don't know if this is related to differing methodologies or what, but maybe the race isn't quite as tied as I thought it was.
