Why are you disgusted with the behavior of the democrats?
Well, the Wikileaks revelations rubbed me the wrong way. 1) the leadership basically putting its thumb on the scale in favor of Hillary + the super-delegate system (not sure it would've mattered, but...); 2) the other e-mails that tried to play up Bernie's Judaism and secularism.
Then after the election, they still seem to be tone deaf, despite the electoral college system punishing them for being exactly that. The same people, the same money, the same wishy-washy strategy... it's as if they haven't learned anything.
With all that said, I have a different level of disgust for the cat-grabber-in-chief and whom he's surrounding himself with.
