The historical conventional wisdom around the US's political parties is that Democrats fall in love (meaning that they abstain from voting over minor political differences), while Republicans fall in line (meaning that they hold their nose and vote for whoever the party ticket is). That's changed a little bit over the the last decade, but not appreciably so.
American politics today are about thesis/antithesis, where the thesis is whatever the latest liberal agenda is and the antithesis is everyone who normally disagrees with each other, but is united in a common disagreement with the Democratic Party.
In this environment, there's only one political thesis (not antithesis) that has more than a very small percentage of the vote.

I want to blame politicization and very clear 'us vs them' sentiment, but I am no longer certain that is the entire reason for current craziness. I am not sure non-tech people understand what is at stake.
To me it is an episode of Dark Mirror 'The entire history of you'. And they do not get it why it is a very bad idea to make a new normal.
