How much can Boehner actually want this job at this point? Granted, someone becoming Speaker at all is a good indication that they're ambitious beyond reason, but once Romney lost, he had to know his job would be wrangling a bunch of nutjobs who think of him as mildly treasonous, as they careen from one near-disaster to another, without anything to show for it in terms of accomplishments or legacy.
It's like being the Raiders coach. It'll be shitty and you'll have a bad track record by the end of it, but head coaching jobs are so hard to get, you might as well take it.
