I'm not a dem or rep. I agree (and disagree) with parts of both platforms. I consider myself a swing vote. If I had to do it over again I'd still pick Trump over Hillary, she's just to easy to dislike. If the Dems would have went with a more moderate candidate (niether H or B fit that category) I think the election would have been less polarized and Dems probably would have one.
For 2020, I see Dems moving even further left, which is a tactical mistake. It's already happened in some of local races.
