“Vote Blue No Matter Who” *is textbook cultish behavior and has lead to some truly awful candidacies.
The post-Obama turn from casual social liberalism to BlueAnon party jingoism has been absolutely miserable for intra-party Democratic politics. The influx of Bill Kristol / Michael Bloomberg / Lincoln Project anti-Trump Republicans is a poison pill that’s going to do the same damage to the Dems that it did to the GOP under Bush.
I’m already seeing all the toxicity and nastiness in local Dem organizing meetings that I remember my parents complaining about as liberal Republicans during the 2000-era turn.
