I think Sarah did a head-fake on Greta’s show to see if Christie would enter the race.
Seriously, the support for Paul and Romney is about 31% combined (RCP). That means 69% do not want Paul or Romney.
This 69% is waiting to vote for a conservative they trust. Perry started to attract this group, but isn’t as perfect as he first seemed. Cain is now the anti-Perry, Romney and Paul.
If Christie does not enter the race, and Palin does, it will be interesting to see how the 69% crystallizes around one of the remaining candidates. I think that once Palin decides whether to enter the race (I think she will...) then the crystallization will occur quickly and the race will be down to Romney vs. Perry, Palin and Cain.
I think Cain’s money will run out and Perry will fall behind. Then, the primaries will determine if Palin or Romney will be the candidate. I predict lots of cross-over primary voting (Operation Chaos II) and it will be a 50-50 race to the end.
FWIW.
