The result is a textbook case of a collective action problem. Most Republicans agree that a government shutdown is a bad idea that will hurt their party. Individually, however, they believe that opposing the bill is good politics for themselves. Thus the rise of the "vote no, hope yes" caucus—or, in the words of Homer Simpson, the "Can't Someone Else Do It?" coalition—of Republicans who want these bills to pass even as they personally refuse their support. Of course, this is free-riding to a degree; if no Republicans voted in favor, the bills would fail, so the vote-no-hope-yes group is receiving the benefit of averting a shutdown while letting any political cost fall on their yea-voting colleagues. This behavior prompted a scolding from House Republican whip Steve Scalise, who recently circulated a memo to House Republicans complaining that “Too many in our conference are falling into the pattern of voting no on tough bills while actually hoping the bill passes because they know that the outcome will be even worse if the bill fails.”
Ryan ascended to the speakership while pledging a return to regular order and by assuring the House Freedom Caucus that he would not cut them out of policy-making. He's arguing now that these promises shouldn't apply to the current spending bill, which executes the overall budget plan negotiated by Boehner on his way out the door. On the other hand, the arch-conservatives aren't making things easier for him either, as they are proposing and supporting a number of policy riders that would cause Democratic support to disappear if they were actually included in the law—even though many of them will vote against the overall bill whether or not the riders are included. Ryan clearly enjoys much more good will among the hard-liners that Boehner had by the end of his speakership, and it's likely that he will resolve these matters before the government is scheduled to shut down. Clearly, however, the basic dynamics that caused Boehner such grief have not been fundamentally affected by his departure.
