Let me ask you something then...how come, once the ACA got "forced down our throats", the republicans couldn't even find ONE of those bills to try and address the shortcomings of a bill that was basically created by teh Heritage Foundation? Not one. Just repeal.
And they had a helluva time finding any of those hundreds of bills when Donald T Rump and a Repubican congress had an opportunity to showcase how it REALLY needed to be done. Despite the fact that Republicans could have whipped out some of those hundreds of bills (but didn't) and perhaps sought to improve rather than repeal, and ended up doing nothing. I'll bet you a dollar to a donut that "Obamacare" is mentioned in the 2020 elections.
