To your opening question - I certainly hope so.Is it possible that the GOP's descent in MAGAland and the Dems' descent into Bernieland could clear the path for a realistic alternative that stays within an arm's length of the political center?
Or will too many center-right, MAGA-averse people keep voting Republican to oppose the Berniecrats...and too many center-left Bernie-averse people keep voting Democrat to oppose MAGA?
It's not lost on me that Donald Trump, with all his baggage, still managed to get 95% of the votes from Republicans.
It's long been a matter of absolute certainty that a viable 3rd party is an impossibility. I've always subscribed to that view. But nothing is permanent.
Interestingly, Bernie never joined the Democratic Party despite his promise to do so. He's still an Independent.
As far as MAGA goes, Republicans identifying as MAGA were a (loud) minority of the party until just before the election when they reached 55 percent. Now they're up to 71 percent. Yes, I hope that shrinks considerably with the growing unpopularity of the President and even more when he's no longer President and relatively irrelevant. If not, I'll also join you in feeling party-less.
