The main reason Republicans are quickly choking on their proposed repeal of Obamacare is that it was so well constructed for this moment.
The AMA, doctors & nurses orgs, AARP, hospitals & others oppose Obamacare repeal in large part because they're stakeholders in it. Paradoxically, the inclusion of institutional stakeholders is what caused some who identify as "on the left" to oppose Obamacare in 2009. Nothing short of government-administered "single payer" was acceptable to those Obamacare opponents as it was being legislated.
Interestingly, the state of Vermont - with support of its governor - tried to enact single payer, titled "Medicare for All" but balked after its true costs became evident: an 11.5% increase in state payroll tax plus premiums as high as 9.5% of a person's income. While *I* could and would justify such high initial costs for single payer health care, most consumers & voters would quickly reject 'em. The sad truth is that had "Obamacare" been "single payer" the *easiest* thing for the GOP right now would be to dismantle it.
What makes it so difficult for the GOP to repeal Obamacare now is that, again, it gave stakes to many institutional sectors. Purists oppose sharing power with sectors that already have it because, they say, it perpetuates existing unfairness. However, you know what else perpetuates existing unfairness? Not having a workable plan or a durable coalition to defend change once enacted!
The defense & protection of Obamacare is not an academic or ideological exercise for 20 million of us whose lives it saved. If it is going to continue to keep us alive, that's because it was constructed carefully in a way to resist today's GOP challenge to it! Likewise, Obamacare was constructed with "booby-traps" that, if it were to be repealed, would bring swift electoral death of the GOP. Its "repeal" would lead to an unintended "replace," the replacement of the GOP Congress as soon as 2018. That's how well it's designed.
Remember also that presidents Truman, Eisenhower, JFK, LBJ, Nixon, Ford, Reagan, Bush I, Clinton & Bush II all called for health care! But only a community organizer, Barack Obama, was able to organize its passage after more than a half century of failed attempts. Today some of the same "purity progressives" who opposed ACA for its lack of public option or single payer are among its loud defenders. In 2012 some called for primarying president Obama because Obamacare, they said, didn't go far enough. Well, now they know better!
The construction of Obamacare and the "coalition of stakeholders" that now defends it was political genius. The GOP is in trouble. The GOP is damned if it repeals, and damned if it fails to repeal Obamacare. That's exactly how the plan was intended back in 2009! So, #ThanksObama for designing health care in a way that anticipated attacks upon it. That's what organizing does! End memo.
