The reason I was skeptical is that I had previously read a very informative breakdown of the various House Republican factions by David Wasserman and Amy Walter at The Cook Political Report. They looked at 5 votes this session and plotted the various Republican factions based on how often they voted with Speaker Boehner:
* 46 "Dependables" 5 out of 5 times,
* 40 "Allies" 4 out of 5 times,
* 59 "Helpers" 3 out of 5 times,
* 52 "Skepticals" 2 out of 5 times,
* 25 "Agitators" 1 out of 5 times, and
* 19 "Rebels" 0 out of 5 times.
Washerman and Walter summarized these divisions further by calling the first two groups the "Coalition of the Willing" (86 members), the second two the "Deciders" (111 members), and the third two the "Coalition of the Unwilling" (35 members).
What is really interesting is that they also compared these divisions to a similar breakdown they did in the last Congress prior to the 2014 midterms. While it's true that Republicans gained seats, the shift that happened isn't in the direction that is commonly assumed.
So far in 2015, the distribution of House Republicans looks less like a bell curve and more like a see-saw in which the ranks of Republicans willing to vote for bipartisan measures have tilted up and the ideological, anti-spending flank has tilted down. The "Coalition of the Willing" has increased from 61 to 86 members, while the "Deciders" - the critical group to watch in upcoming fights - have remained stable and the "Coalition of the Unwilling" has fallen from 63 to 35.Just in case you are wondering, the likely next Speaker of the House Paul Ryan is one of the Dependables. So it should come as no surprise that - while he criticized the process that led to the budget deal - he plans to vote for it. If Boehner simply rallies the rest of the Dependables to vote with him, the deal will likely pass (as long as it gets broad support from Democrats). If anyone is worried about the left flank of the Democrats in the House, Co-Chair of the Congressional Progressive Caucus Keith Ellison has announced that he's a "yes" on the deal.
There is no way of knowing what the final vote tally will be (Rep. Bill Flores predicts 70-90 GOP votes for the deal). But this information tells you a lot about why John Boehner had the confidence to negotiate an end to the chaos created by the Freedom Caucus as his parting "gift" to the malcontents.
