A lot of this is due to the blatantly undemocratic actions Republicans have been taking to maintain their hold on power. There was a lot of this sort of familial strife during the run-up to the Civil War. Both sides, for different reasons, feel increasingly frustrated that their political wills aren't being fulfilled, and Trump's pure recklessness in, basically stating that he won't accept any result that isn't a victory, is making Democrats feel that nothing short of a landslide will ensure that this mess won't get worse. Peaceful power transitions have historically been one of America's great advantages, look to our Southern neighbor for just how not having that can hold us back.
