With Obama approval ratings in the 30s...
Obama vs Gingrich

Obummer in 20s approval rating and failure...
Obama vs average Republican vs moderate Independent
The first 3 maps are extremely Pro-Obama. If he had approval ratings in the 30's Gingrich and Romney would have a comfortable lead, while Palin would be neck and neck with Obama. I mean, you put Florida for Obama against Gingrich. Obama's approval ratings are already low in the state. Just think what will happen to them there if his national approval rating drops 20-30 points.
Also, if his approval ratings were in the 20's, I doubt he woud even with the primaries, and if he did, it would be a 45 state landslide.
