If Palin doesn't run or win the nomination, she will end up being kingmaker to whomever the republican nominee is. She's also guaranteed at least one night as keynote at the convention should she not be the nominee.
FYI, I think everyone is underestimating her potential strength in New Hampshire and Maine (particularly Maine).
My choice of what are we wrong about: Romney being the nominee.
Lol, she doesn't have a shot at winning N.H or Maine in the Primary, if she does win either of those states she would get DEMOLISHED in the General in both and well nationwide as well.
