More than two years before the 2012 Iowa caucuses, presidential speculation should come with a soothsayer’s money-back guarantee. But what all the discussions of Palin’s future miss is the way that Republican Party rules are made-to-order for a well-funded insurgent named Sarah to sweep the primaries before anyone figures out how to stop her. If Palin can maintain, say, 35-percent support in a multi-candidate presidential field, then she is the odds-on favorite for the GOP nomination…

If Palin launches a 2012 race – and survives the South Carolina primary with her aura intact – she could theoretically sweep the winner-take-all states without ever winning a majority anywhere. The Republican establishment (the congressional leadership, the governors, the major donors and national consultants) could all agree that Palin would be an electoral disaster against Obama in November and still be powerless to halt her juggernaut.

The best way to stop Sarah would be for GOP insiders to rally quickly around a single anti-Palin candidate. But such cabals rarely work in politics because there are too many egos involved.
