It’s not an accident. The country is moving left, and the right-wing Democrats are afraid of losing control of the party. They almost did, twice. They don’t take the “the other guy is Hitler” rhetoric seriously, themselves. They aren’t worried about losing their power if the Republicans win the Whitehouse, or even both branches of Congress, because it’s all one big club, and they won’t be kicked out, as long as they go along to get along, but they are terrified that a leftist rise will take the reigns of the Democratic party from them, and then they really will be out of power.
