I see the democrat party as a whole. Birds of a feather flock together. Therefore, they have a similar value system. Some are more extreme than others.
Right now, there seems to be a breaking away from the democrat party in the smaller circles of politics. Some are seeing the socialist take over, and don't agree with it. Those who stay either fear they'll be replaced if they leave, or agree with the current policies of the extreme left, i.e., Marxism.
