That's her strong suit right now as I see it.
She may not run, but she's a shot in the arm for conservatism, and that is GOOD.
It remains to be seen whether or not she will be the best candidate we can come up with in '12.
The most likely field: Pawlenty, Huckabee, Romney, Palin. Dark horses: DeMint (a senator who probably won't run), Barbour, Jindal. 1%ers: RonPaul, Keyes, Hunter (and a few other nut jobs).
The governors of New Jersey and Virginia may be great candidates in 2016, but they're not going to run yet. If anyone can remind me of another realistic candidate I've forgotten, please add to this list.
