2016 showed a real schism in the (D) party. I was a "BernieBot" myself, but held my nose and voted for Clinton when it was time to put the peddle to the metal. Two of my daughters (them what live in VT), however, sat the election out and refused to vote at all. On the other side of the spectrum were many of my oldest friends, all women in their 60s and 70s, who adore Clinton and continue to this day to bash Bernie supporters.
Everyone is still on the fence about the current crop of (D) presidential candidates. But take note, Trumpanzees -- without exception, in all of the (D) political talk I read and engage in daily -- to a person everyone says that it whoever ends up as the (D) nominee, they will vote for him/her to get the Toadstool out of our White House. It is a very positive sign that (D) voters are very energized and engaged this far out. Wait till 2020 and watch what happens!
