Mitt isn’t really gaining momentum, and there really isn’t much higher he can go. All those 2s 3s and 4s add up to 10. Huntsman, Pawlenty, Santorum, other establishment candidates, really aren’t taking off, because Romney has 30 % of the establishment half. And Perry is taking some establishment money from Romney. There’s still the tea party half, where Palin would be comfortable.
If they are broken down to pluralities within their base, and the TEA partiers unite behind a single candidate, then the TEA partiers will prevail, not just in the election, but in shaping the future of the Republican Party.
