I have confirmed with a group of Congressmen that House Speaker John Boehner will not be reelected Speaker tomorrow.
He will either resign or be forced out tomorrow.
Only 17 members are needed to block Speaker Boehner's election tomorrow. A Speaker needs an absolute majority of all votes cast for a specific person.
If no one has a majority, the House is speakerless. I've confirmed these rules with the House Parliamentarian.
