Steve Kornacki has a plan (via The Dish):
[T]hose who just want her to go away should consider a Palin presidential campaign an investment: You’d have to deal with a few weeks (or maybe even months) of saturation coverage, but there’d be a good chance it would all end with Palin’s presence in our lives severely and permanently diminished.
John Sides fights this notion:
[H]ere’s another way to make Palin disappear: have a presidential election in which she is not a candidate. The surest way to sideline any prominent Republican politician between now and November 2012 is for them not to enter the race. Indeed, even those that do enter the race will be sidelined by not winning. The candidates, and then the ultimate nominee, will suck up virtually all of the oxygen.
[S]hould she back off this time and the Republicans lose, the tease will start again right around the time that the polls close on the west coast, and it won’t let up for the next three years. Losing this time around — not informally through testing the waters and backing off, but with a solid defeat at the polls in Iowa and New Hampshire — is the best way to prevent that. Well, other than having a different Republican in the White House.
