Bwahahahaha! Well, I didn't expect Ryan to actually pull the bill before a vote, but I still find the outcome hilarious.
This was a damned-if-you-do, damned-if-you-don't situation for the Republicans. On one hand, it was, "Pass the bill, hurt millions of Americans, piss off the moderate Republicans for hurting people, and piss off the conservative Republicans for not taking enough away, and risk losing seats at the next election". On the other hand, it was, "Don't pass the bill, piss off the conservative Republicans legislators for not doing enough, piss off the conservative public who wants Obamacare gone, make Trump look weak, and make Ryan look weak, and risk losing seats at the next election."
Any way you sliced it, the Republicans were screwed for coming up with such a lousy bill in the first place. And why was it a lousy bill? Because, as Boehner noted previously, Republicans can't agree on what healthcare reform should look like. It's easy to propose full-repeal bills when you know they're not going to make it past the President's veto (ala, what the Republicans did over and over during Obama's term), but when the Republicans finally had the power to pass something, they couldn't pull it together.
Of course, Trump and the Republicans will blame the outcome on the Democrats, because obviously the Democrats should go along with whatever the other party wants. But the reality is, this failure is firmly on the Republicans' shoulders.
I couldn't be more thrilled unless the bill had actually come up for a vote and failed.
