The Democratic party can make a person crazy at times, but in general the values of the party are ones we believe in. One of those values is that we protect the vulnerable in our society/world even though there may be cost to us personally to do this.  And we believe many Democrats feel the same way.  If you wish to consider this voting in our own self-interest, then think what you want.

Democrats’ priority in this last election cycle was to protect the vulnerable—LGBT individuals, minorities, women, children, the environment, people from other cultures here and abroad, people with illnesses, etc.  Too many Sanders’ supporters lost sight of this value—blasting away at the only institution that has, over the years, protected people, turning people who should know better against the party.  And now people are actually being killed because Trump/Republicans have unleashed hatred, and that's on Sanders and too many of his supporters.

This was a winnable election for Democrats.
