The GOP's healthcare ambitions died because John McCain decided he wanted something vaguely called "regular order." Collins and Murkowski were no votes, the GOP needed everyone else on board, and John McCain said no, not because he opposed the GOP on substance, but because the process deviated from "regular order."
Regular order isn't really a thing. Why? Because there's no such process, spelled out formally in the rulebooks called, "Regular Order: Section __, Part __" It is just a term we use, informally, for anything that isn't too batshit crazy. Basically, it is the "Schoolhouse Rock" version of how a bill becomes a law, or something not too far from it. Bills are introduced, sent to committee, debated, marked up, blah, blah, blah. There are lots of ways that a bill can deviate from the purest form of regular order, whatever the hell that is. In fact, the late Barbara Sinclair wrote a book called Unorthodox Lawmaking about it. In its first edition, the procedures really were "unorthodox" in the sense that they were deviations from the norm. By the fifth, and alas, final edition (unless one of her students takes up revising the text), the problem was that the procedures had become normal, and hence no longer "unorthodox" by any meaningful definition of the word. What, then, is regular order? Is budget reconciliation regular order? It is a deviation from Schoolhouse Rock, but it is increasingly common, and can still incorporate the other aspects of "regular" order. The GOP just decided to skip those other aspects on healthcare as a strategic matter.
However, what is happening this week, which is truly important, is that Mike Enzi, chair of the Senate Budget Committee, will begin holding hearings to mark up a budget for a $1.5 trillion tax cut. That's right! Committee hearings and markup! Regular fuckin' order, or some approximation thereof!
Yes, the GOP will be using budget reconciliation. That's... not quite "orthodox" lawmaking as Barbara Sinclair defined it back in the first edition of her book (I still have a copy on my shelf!), but the Republicans are going through committees with hearings, debate, markup, and everything else. None of that last-minute, behind-closed-doors shit which was really what got John McCain to turn on his party. Note, also, that this was the process the GOP was afraid to use on healthcare.
I know, this is difficult. Trump is going to keep saying crazy shit about Puerto Rico, maybe stir up some stupid fights about sports, and who knows what else? Actually important stuff is happening. Mike Enzi is boring, but pay attention to him.
