If we look at realclearpolitics things are really, really wierd:
http://www.realclearpolitics.com/polls/
They have Gallup Tracking listed at 46-43 Obama and Rasmussen Tracking at 49-45 Obama... sandwiched between 15 point lead in Newsweek and 12 point lead for LA Times. I don't think anyone knows what's going on.
