If i could change time to allow Biden to run, i would do so only because Harris running in the situation that she did, didn't work out regardless.
But I kind of don't think he would have won either. The debate performance plus "his bad economy" I think we're too impactful. I think the only chance, if any, was Biden not running, and us actually having a chance to select a candidate.
The biggest hurdle I would say is the disinformation war that reality is losing against Russia/MAGA.
I actually don't think so. Like I speak with Republicans that are very dismissive of covid still, despite having family members die to it. If people were bothered by his covid response, they would continue to be bothered by the fact Trump shit the covid response. Instead it seems voters think everything was fine during his term (completely uninformed or unaware of the fact that he was impeached twice, raped women, a good friend and neighbor of Epstein, and tried to overthrow the government)
The apathy maybe comes from how Harris was hand picked (because it was so last minute that Biden dropped off) vs us having an actual primary with several democrats.
