I'll hold my nose and vote for Hillary Clinton, but I'd avidly support Elizabeth Warren. It's the ideas, not the gender/sex/race. If it were, I would've voted Romney over Obama -- although I was considering voting McCain pre-Palin.
The fact of the matter is, to a lot of people, Hillary is a more-of-the-same candidate with a hawkish streak and Wall street in pocket. Meanwhile, price inflation makes things seem to cost more while currency inflation continually nickel and dimes at wages, and nothing's changed for the better for a lot of people. The ACA didn't do much for them because they are primarily employed with insurance plans available to them, for instance.
What has Obama accomplished to make their lives better, and why hasn't the DNC backed them up? Instead, we saw multiple cases across the country of people distancing themselves from his policies, and losing. Badly.
Now the House and Senate are under Republican control, at least until November, which is why it's paramount we get ANY Democrat in there. I'd vote for a tattered cardboard-soled boot over Trump.
