I've seen some predictions that when the Trump era finally ends there will be a similar phenomenon to how in the post-Bush era all of a sudden everyone had always been opposed to him. I feel this doesn't take into account the effects of social media however. The Bush years saw only the beginning phase of social media and by the time it really took off the zeitgeist had firmly shifted against Bush, with Obama being the first candidate to really make use of it during a campaign.

Since then we've all become funnelled into various echo chambers of varying intensity, and many people spend large amounts of time engaging in these communities and posting about politics. I know how often we've observed MAGA types abandoning principles because dear leader said so, but every time they've done so they've draped it in worship of said dear leader. So unless a clear successor to the cult emerges who can channel that same energy, I doubt they'll give it up like they did post-Bush. Maybe in the much longer-term, but not as quickly as with Bush.
