It may well collapse no matter who wins
Honestly, I see almost no way around it.
Perhaps the more important question is, whom can we elect who can (or even wants) to rebuild the wreckage - and will the American people have the fortitude to gut out the sacrifices required or will they fall for a tyrant who makes more promises? It will take many years and most politicians aren't in anything for the long haul. That's why we are in this nasty situation in the first place.
