Awesome. To me, only slightly reading between the lines, it sounds like he is suggesting exactly what I feel is the right track here.

Let Trump do whatever it is that he is going to do. If individual elements / components of his policy suggestions are good, help him with them. And if/when he suggests dangerous, counterproductive or bigoted things, call him out, dig in your heels, and do everything you can to raise awareness and stop him.

Let Trump dig his own grave trying to fulfill all of his contradictory promises to a large angry mob.

But in the meantime, don't obstruct good things simply because they came from the "wrong side". That has been the Republican modus operandi -- show the people there is a better way. Trump talked about rebuilding infrastructure in his victory speech. FDR's "New Deal" did a lot of that with the Tennessee Valley Authority and other projects. That created a LOT of jobs and helped pull the US out of the great depression. Any infrastructure / public works stuff that Trump pushes for that would actually have positive results while creating jobs? Sign off on that shit!

Trump's Wall could be a fulcrum point. Pointless and somewhat offensive in premise, but some good could come from trying to build it or even actually succeeding (which I find highly unlikely). I think the appropriate response to Trump's Wall for Democrat legislators would be to vocally point out that tax money would probably be better spent elsewhere, but otherwise playing along to a certain extent. That wall is going to be a big millstone around Trump's neck -- no need to work overly hard to help him try to wriggle out of it.

Jesus, Wolf Blitzer is such an idiot!

At least Wolf Blitzer generally allowed Bernie to speak without interrupting him, that's the best I can say about his part in this interview.
