Honestly, Trump and a few of his successful business leader appointments must look at both sides of the aisles,and say "how do some of these guys have a job"? Even as an outsider living in a socialist nation, even I shake my head at this.
Ironically, the Democrats have as much if not more to lose by this, as Obamacare is going to falter and the GOP can rightfully suggest that from Day One Schumer said that repeal had to be off the table or he would direct his Groupthink minions to not vote. The GOP have received exactly zero votes and zero support from the Dems who surely realise that Obamacare was a great big, socialist scam meant to trap all future governments and societies within the ACA Bill.
I will say this, two important issues, one, trying to roll back once earned benefits that are now deemed entitlements is very hard to do, two, the costs of healthcare from doctors on down is quite expensive and thus unsustainable as a socialised option. Especially when you are already stretched with 11 million illegal immigrants and foreign government abuses against U.S businesses.
