A complicating factor now and early next year is that House Speaker John Boehner (R-OH) enjoys the perks that come with the job and is loathe to give them up. To keep his job, he must placate the 144 members of his party who voted against the Senate bill yesterday. But doing what they want is unacceptable to the Democrats, who control 200 seats in the House. A lot thus depends on what the more than 80 moderate Republicans who voted with the Democrats yesterday want, but they are not organized and do not speak with a single voice. If they did, they could work with the Democrats and run the show.

Boehner will almost certainly keep his job, in large part because nobody else wants it. The Constitution says the Speaker is elected by the entire House--not just the majority party. Thus anyone who has visions of replacing Boehner somehow has to convince 218 Republicans to support him (because he won't get any Democratic votes). Given how fractured the Republican caucus is right now, that is a very tall order.
