John Boehner may be the worst Speaker of the House of Representatives ever to serve. I'm not the only one who thinks so: http://capitalgainsandgames.com/blog/stan-collender/2749/cliffgate-will-be-boehners-waterloo.
I've made the comment that if Boehner choose to act rationally, and allow a clean CR and debt limit bill to the floor for a vote, the measure will pass with a majority of Democratic and Republican Representatives voting for the measure. Boehner will immediately be challenged as Speaker by one or more members of the Tea Party faction of the Republican Party. He cannot receive a majority of the votes required for him to remain speaker. He will be replaced, although it's far from clear who will succeed him, and if it will be a Republican or a Democrat.
If Boehner brings measures to the floor with Tea Party inserted "poison pills" for votes, they will not pass the Senate nor be signed by the White House. The United State Government will remain shut, and the country will default on all or part of its debt. Boehner will lose the Speaker's chair, and be largely responsible for the default of the United States and all of its intended and unintended consequence.
With the first, he maintains a tiny modicum of respect and capability; with the second, he becomes one of the most reviled figures in American history and politics. Should be a pretty simple choice.
