A Republican Obamacare will coat the GOP the House, Trump a possible 2nd term, and the US what has been the best healthcare system in the world. There will be no opposition once the GOP passes Obamacare 2.0 in its own name.
Leaving Obamacare as it is would cost the Republican party everything.
Questions become....Do they care?....Does it matter which party is in control (supporting the uni-party belief)?
This is Trumps administration and I hope he's as smart as I believe he is in order to fix the damage that's been done.
