All personal observations, so take them for what they're worth, based on the relatively few people I've asked: (1) I don't know a single confident Democrat. (2) I don't know a single person who voted for Trump in 16 who is voting for him again, though many are voting 3rd party or not voting (had drinks with a good friend last night who wrote in his wife!). (3) The engagement and involvement of my more liberal friends is unreal -- day after day after day of posts encouraging people to vote that I never saw in 2016.
