In 2016, Dems funnelled energy into anti-Trump movement. This time I suspect something more like a circular firing squad will occur. There is plenty of blame to go round and if they lose the House, they don’t have an obvious venue for opposing GOP so focus will be on intra-party.
Somehow, some way, the media and the people who run the Democratic Party will figure out how to blame this all on Bernie Bros.
That train is always on time.
