For political junkies it doesn't get much better than this -- the Republican nomination battle. Mitt Romney hangs in there to deal with one challenger after another (Michelle Bachmann, Rick Perry, Herman Cain, now Newt Gingrich).
My hacked-together chart below, based on CNN polling data, shows how Romney has largely held steady (small decline of late) from September to today. But look at Gingrich in red, feeding off the decline of the Cain Train as it feels the effects of the various accusations. Perry dropped after bad debate performances and his odds went down even more this week as he confused the voting age. Political junkies grab your popcorn, because this Romney-Gingrich fight is gonna be a good one.
