Ross thinks the Republican party is closing ranks:

Oh, the pundits will fight, as they have been for a while, but for a serious circular firing squad you need the activist groups to turn on one another. You might think that a defeat like the one the GOP endured last week would prompt Grover Norquist to argue that the Republican Party needs to ditch its warmongers and its theocrats, or prompt Tony Perkins of the Family Research Council to argue that the GOP needs to ditch its flat-tax obsessives, or prompt the Federalist Society's Leonard Leo to complain about all those anti-intellectual hicks who loved Sarah Palin. But in practice the incentives probably cut the other way: Nobody wants to fire the first shot against their fellow movementarians, because then everybody else might just close ranks and train their fire in your direction.
