If she sees the RiNO Establishment, with its serried ranks of Murkowskis and McCains and Bushes, successfully tigering down the Tea Party with money and backroom deals and brutal, bare-knuckle ad hom advertising against the Tea Party's standard-bearers (who right now appear to be Santorum and Gingrich), then I think she might conclude that there is nothing for her to lose, if the RNC crowd wins again, and throw herself on the pyre in an attempt to forefend such an outcome, by using her fading influence to help whoever can beat Willard.
There have been several indications -- Obama began his campaign this week by savaging Romney -- that Willard is the one the 'Ratscum really want, and have wanted, all along. That being so, his nomination simply must be prevented, and I'm sure she sees that.
I think she might indeed try to enter some of the primaries late, in order to try to prevent Willard from sewing up the nomination by "achieving inevitability". That would open the convention to a real fight on the floor, such as the GOP hasn't seen since 1952.
The problem is that, as I write this, I am just back from checking the news and it looks like Gingrich is fading in Florida.
I don’t think it will necessarily be all over if Romney (or, for that matter, Gingrich) wins Florida. But “achieving inevitability” could, possibly, be within reach to either of those men next week.
Gingrich has a high mountain to climb if he loses Florida. No debates are scheduled and the next states are said to favor Romney, and there is at least one state with a lot of delegates (Michigan, IIRC) where Gingrich failed to get on the ballot.
Palin may have been pushing Newt forward — by her SC gambit — to see if he would sink or swim, intending to jump in and save the day if need be.
Hard to wrap my head around whether that would work right now!
We’ll just have to see how things develop.
