Just a few nits to pick, Irv.
If political campaigning in the US is even remotely similar to Canada, parties tend to campaign from more extreme positions, in order to make the base happy, then, if elected, govern closer to the centre. So, although the NGD and student loan forgiveness might scare people on the right, those policies are probably the first to get dropped after winning the election. Well, there may be portions of the NGD that might be pursued, but certainly not it's entirety. And, I really don't know what you find so scary about universal health care.

How would it be paid for? Through taxes, of course. That would be offset by what you wouldn't pay in insurance premiums. UHC began here as provincial efforts back in the 1940's and by 1961, all provinces had implemented plans. The federal government implemented UHC as a national program in 1966, which standardised services across the country, as well as kicking in federal funding. At the time, many doctors and, of course, insurance companies campaigned bitterly against it as creeping communism. But, they lost that debate. There is still room for private insurance, which provides drug coverage and other services and equipment not covered by UHC. It certainly isn't perfect, but what system is? If the US were to implement UHC, I would skip over looking at our system to copy - there are better ones in Europe.
As for Bernie being a "multi-millionaire", I suppose - technically - he is, at a net worth of $2,000,000. So, one might consider him rich, but that's debatable. He might be rich to an inner-city person living on minimum wage, but to the truly rich, he's just another peon.

We may not have a dog in this electoral fight, but what happens in the US affects us, so we take an interest. But, not the Russian-style "take and interest", of course
. In the immortal words of (former) Prime Minister P.E. Trudeau, "Living next to you is in some ways like sleeping with an elephant. No matter how friendly and even-tempered is the beast, if I can call it that, one is affected by every twitch and grunt."
