Your post is the first time I have ever seen mention of Trump addressing single payer favorably. (I take that back. There was this group of supporters for another guy who repeated that non-stop for months even though you would link them to his comments stating otherwise.)
He has been advocating for increased competition in the private sector since he announced his candidacy.
That’s what his comments about unleashing insurance companies to be able top compete nation-wide were all about.
Exactly, that is all I’ve heard Trump discuss is competition in the market. That is quite the opposite of single payer.
I don’t believe for a minute he is using a single payer system.
I also believe there will be bidding on pharmaceuticals by more than Medicare & Medicaid.
Here is a Google search list of articles about Trump and single payer.
Here are a few examples from that list:
Trump Pushes Single Payer Healthcare, Tax Increase on Wealthy
Donald Trump wants to replace Obamacare with a single-payer health care system, GOP congressman says
Is Donald Trump still 'for single-payer' health care?
Head of nurses union 'counting on' Trump for single-payer system
Like many of his other positions, nobody really knows how serious he is about single payer, or in what form it would take, until we see an actual bill from his team.
My own personal way to help solve the healthcare "crisis" is to force hospitals that accept any federal funding to charge the same rate to the uninsured as they do to group insurance companies, and to use the Interstate Commerce Clause (properly this time) to allow insurance companies to sell across state lines and for a person to maintain their same policy no matter where in the country they move to.
