Rasmussen poll out today puts Paul down 8 head to head against Obama. Both Gingrich and Romney are now positive against Obama.

"Today" is the key. I've been watching Rassmusen bounce all over the place in the last year. They are always days & weeks behind the curve. It's a useful snapshot of a moment, but that's it. Newt was trouncing everyone in Iowa a week ago -- now he's in a dead heat.
With the speed of information today, these polls are just not as reliable as they once were. Rsamussen took weeks for Cain to show the beginnings of a slide downward and by that time, he was already in the ditch and suspended his campaign.
