You would think so, but he remains as a sort of zombie. trump is the presumed nominee for 2024. There is no obvious way to prevent that.
It reminds me of when the Neo-Cons collapsed. Their entire strategy was completely disproved by reality. They failed in every way imaginable. Their ideology had no place for non-state actor in international relations, and yet Al Qaeda existed. Their think tanks went bankrupt, no one was interning with them, phones were disconnected, no one was admitting to be a Neo-Con, Republicans were desperately trying to say everyone else was a Neo-Con....
And yet they still controlled the White House and all foreign policy for years afterwards. Heck, Bush was reelected afterwards, and kept the Neo-Cons in power.
It is the same way with the alt right. They still have a huge amount of power, but they are ashamed to admit who they are.
