I'm not "blaming" the FC for anything. If they want to stick to their guns and not bend, fine; that's their call. But, in the same way, Trump is under zero (0) obligation to bend for them.
Yes, the political calculation Trump & Co have to make is how much he would lose and how much he would gain from doing so. Sure.
Politically, he's between a rock and a hard place. He's essentially dealing with three parties here. So he has to decide to stay in that position or to work with the one that is most willing to work with him.

You did blame them in you're first post. And those who stuck to their guns are plenty willing to work with trump, and what HE promised to voters. That bill was not what he promised. It's trump who wasn't willing to work with them. GOP owns HOUSE, SENATE, and the WHITEHOUSE. There is no reason to put out a bill that's far left of center, which is what that was, sure a little right of Obamacare, but still a bill GOP would never ever put out unless Obamacare was there. He and republican leadership backed this bill because they were afraid of dem scare tactics. If the left owned all three houses like the GOP does now, they'd never even consider the rights objections, like they did with Obama. I thought trump was supposed to be the one whose not scared of the media or any of the Dems. Clearly he is.
Trump should sit back, and let republicans vote like they did 60 times before he was in office, and do a full repeal of Obamacare...like he promised.
