A lot of people I know in Bisbee are going for Bernie and I guess I know why. But in my view his "single payer" strategy is a hasty and opportunistic proposal that isn't going anywhere, even in Vermont.
What we need to learn is that "single payer" doesn't always mean Canada or France or England, the purely socialized systems.
I proposed a "single fund" universal health care for the U.S. in an academic journal about 20 years ago; the point is we can achieve a "single payer" system without abolishing private health insurance. We do this by requiring private insurance to meet government standards and to forbid private insurance to cherry pick, or attracting the well and letting someone else pay for those who are sick or who will likely turn out to be.
With Ron Rouse, I proposed such a system in New York in 1990 and while the late Governor Mario Cuomo flirted with the idea, he wound up not running. The plan details were outlined in Universal New York Health Care, published in The New England Journal of Medicine, September 6, 1990.) Here is a link: UNY NEJM.
