He could solve everything (and probably be re-elected in a landslide) by leapfrogging the Democrats (even Hillary said it was off the table) and pushing for universal health care with some form of single payer. Even if it were a private / public mix. This is one issue that he, at least in the past, has been open to looking at.
"Working out detailed plans will take time. But the goal should be clear: Our people are our greatest asset. We must take care of our own. We must have universal health care."
"We need, as a nation, to reexamine the single-payer plan, as many individual states are doing. But implementing such a plan is not simple. One major problem is that the single-payer plan in Canada is in financial difficulty, as is the nationalized plan in the United Kingdom. We have to improve on the prototype."
-- The America We Deserve, 2000
It may take someone like Trump to convince his blinder wearing maniacal hordes to accept some form of national mandated insurance. After all he could literally shoot someone and they'd still adore him. As we all know, the exact same type of legislation as the ACA was proposed by the Heritage Foundation decades ago, and was implemented by Mitt Romney in his State. It was just that the black Democrat proposed and enacted it that they had a problem with.
If he had the balls to stand up to Ryan and the extreme right and libertarians and push for this and drag his glassy eyed supporters along with him, he'd probably waltz through the next election. So no one tell him please.
Actually it raises a good poll question,
Would having some form of public funded single payer (even if there were a private option) universal health care coverage (finally) be worth having Trump in charge for eight years? Because it ain't gonna happen if Pence or any other Republican is in charge, and the tea baggers etc. would always reject any single payer from a Democrat as being 'socialist' gov'mint takeover, the message helped along by 24/7 propaganda against it from hate radio and Fox News.
