I disagree with, but respect, Sanders, Stein, Warren, Feingold (and some other lefties). Hillary equals revulsion, repulsion. I can't be talked from "respect" to "vote" with someone I can't even respect first.
The D party worked very hard on converting "respect" people to "vote" people. I think they achieved 100% success. The problem is most of the country can never respect her, and there was zero effort put into making her respectable (perhaps it was recognized as impossible?)
There's something fundamentally wrong internally with the D party when the ground seems to be crawling with respectable (possibly votable!) candidates but instead we get a movie caricature of Lex Luther combined with a slightly more chicken hawk bloodthirsty Joker from a sequel rejected in the 90s. There's something just horribly fundamentally wrong with how people gain political power inside the D party, resulting in the wrong leaders at the wrong times.
