Yes, as you, I, and others have said many times, the election results needs to be a complete repudiation of MAGAism.
That won’t suddenly see Trump and MAGA cease to exist as entities, but it will likely start a purge of the ideological zealots from the party, including the party leadership and high administrative positions.

Whilst Democrat control of government is important to reversing the slide in to full-on white Christian Nationalist dystopia (and likely popular response leading to violent, prolonged conflict), the single biggest contributor to the fight against such an outcome (which could still occur even if Harris wins the election) is the return of the Republican Party to at least what it was prior to Trump’s rise (and, ideally, what it was prior to Reagan’s takeover).
