I think it boils down to that there's no practical difference between the parties. The do-nothing Republicans were ("are" if Trump's successor doesn't carry the MAGA torch) going to get us to the same place that the Democrats want to go, just more slowly.

The so-called Right in D.C. do nothing but compromise ever leftward. When was the last time a radical push to the Right was proposed for anything and the Left compromised towards the Right? I can't think of a single instance.
