If John Boehner planned to accomplish something then he’d say so. A partisan player does not pre-emptively hand over the wheel unless he doesn’t want to be holding it when the car hits a tree. Of course, after handing over the wheel he has a strong incentive to make sure that the car does in fact hit that tree.
Republicans aren’t stupid*. Fixing the disaster that Bush left is will be punishingly hard. It demands the kind of compromise that conservatives cite when they spit on George W’s dad, except times ten million. Even if Boehner somehow keeps the teaparty lynch mob at bay and pulls it off**, his name will be anathema and history will give Obama the credit.
So why not let fail? If the country slides a bit farther then grampa Fred Thompson could sleepwalk into the White House. Even the worse case scenario (BOA goes tits up, dominoes, proles starve) isn’t necessarily a disaster for the GOP. These are the same guys who keep flirting with defaulting on the national debt. A little creative destruction doesn’t put them off nearly as much as you’d think it would.
(*) Pipe down. It isn’t that easy to win when the country hates your agenda and doesn’t think much of you personally.
