The question for Republicans is what happens if this fails? It means more turmoil, more evidence that the GOP can't govern, and the risk of another shutdown. By contrast this deal pushes the budget debate past next November and lets Republicans focus on ObamaCare and its many ills. One promise conservatives should exact from Speaker John Boehner is that if this deal passes, he won't do a side agreement with Democrats later to extend jobless benefits. In any case we doubt any other Republican could have done much better than this least bad agreement.
