Larison doesn't think she has much of a chance at the GOP nomination:
If Palin is in so many ways a less serious candidate than Dan Quayle, it is worth remembering that Dan Quayle’s extremely brief flirtation with presidential politics in 1999 ended because he could not find enough people interested in backing him financially.
When there was already more or less an establishment candidate in Bush, no national political figure other than McCain attempted to oppose him, and McCain’s insurgency that year collapsed quickly enough. It seems to me that Romney is shaping up to be the prohibitive favorite and heir-apparent, just as McCain effectively was going in to the primary contests. Aside from his own money, Romney is an effective fundraiser, and he has the experience and the connections from the last presidential run to make it more difficult for any other contenders to gets funds and endorsements. Republican primary voting does not reward insurgent candidates. Barring some unforeseen implosion, Romney will begin as the frontrunner and likely remain in that position. Any contest between Romney, the competent, wonkish technocrat, and Palin, who is the opposite of all these things, would result in a win for Romney.
