All I know is, Republican voters went to the polls in 2010, 2012, 2014 and again in 2016 to repeal Obamacare.
If the voters of a state want insurance companies to cover preexisting conditions, or whatever. That can be passed at the state level and the citizens of that state will shoulder the burden of much higher insurance rates or taxes.
The House is heavily gerrymandered and Republicans are safe unless they don’t do exactly what they said they would do, repeal Obamacare.
Heck give the left a bone if need be and expand medicaid to cover more people, especially many of those receiving subsidies to pay for Obamacare insurance.
But scrap everything else. It’s none of the federal governments business.
