The effects of Trump and the Republicans are likely to be global and so negative that no positive result can make up for them. A new Great Depression, widespread wars and the likely use of nuclear weapons or even a full-on nuclear war. And an America that is fundamentally hostile to the rest of the world isn’t a good thing, either.
People have been telling me for* decades* that “sooner or later the pendulum will swing left”; instead there’s been a slow slide to the right, and now the US is sliding right off the cliff into the abyss of fascism. There’s isn’t any pendulum; there’s a ratchet.
And with the Republicans in a position to implement unrestrained voter suppression and worse it really doesn’t matter how unpopular the Republicans become; they can simply declare themselves the winners anyway. That’s what happens when you put anti-democratic people in charge of a democracy; democracy dies.
