So what efforts has he made to come up with that cheaper, better, and so much simpler healthcare system that covers everybody, and guarantees that even the poorest can have adequate healthcare?
As far as I can see the only thing he has done is made insurance much more expensive.
There is another thing he's doing. Or really not doing
Texas is challenging the preexisting conditions clause protections in federal court. The trump DOJ is refusing to defend the law.
Republicans believe that they have the right to pass laws that legally allow insurance companies to deny people coverage or kick them off coverage because the person got sick. We already went through that with the republican health care reform in the reagan years. Thousands of Americans died because of it. Estimates are that 45 thousand Americans died an unnecessary early death each year because of it.
So their solution is to kick millions of Americans off insurance to force them to die an unnecessary early death.
