Of course I will vote for him. However, I feel that his support for Hillary was sufficient lukewarm that it led directly to the current situation and that the so-called progressives have forfeited any right to calling policy.
From what I have read, he was brilliantly effective as mayor of Burlington and was able to work well with the business community there. But that is a long way from working well with the current crop of deplorables that is the Republican party. So I don’t think his election would change much. He would in fact, have to govern by executive order which has been the case for a couple decades. Just as agent orange reversed nearly everything Obama did any elected Dem would reverse everything Trump has done.
That said, I oppose his candidacy because he is unelectable. Two thousand years ago they crucified a Jewish socialist and not much has changed since them. They would emphasize the socialism, but the other would be in the background for vicious dog whistles (“cosmopolitan” maybe). If the Dems nominated W, I would still vote against Trump, little as I like W.
