What is it about, “it won’t work here,” that is so hard to grasp? If Trump wanted to push single payer onto the US it would be an issue. Since he stated he does not, your death grip on the subject betrays the bankruptcy of your anti-Trump arsenal.
The point is that Trump has stated (and recently) that it works well elsewhere. That is flat out wrong, and, worse, it shows Trump’s ignorance on the issue.
