I think that the main reason is that he was virtually alone in predicting Hilary Clinton’s loss in 2016 and then created a very incisive film about it. He’s been a supporter of Bernie Sanders in past campaigns and consistently argues for an orientation towards working-class politics as opposed to prevailing corporate liberalism of the Democrats. Now some would say that supporting the Democrats at all is a betrayal, but I’m staying out of that one for now.
I just learned about this around 11:45pm ET November 4. I signed up as a swing-state voter, and in 5 minutes got connected with 2 safe-state voters who agreed to vote for Jill Stein as a swap for my (very reluctant) vote for Harris. I feel much better now. :-)
