It's a good question although I think there's still a 50/50 shot Trump gets reelected.
My guess is f the Republicans have a really bad November then Trump will be seen as the major problem and it won't be any of the sychophants of Trump you mentioned (Jordan, Gaetz, Cruz). To lose the House, Senate, and presidency in four years should be a massive red flag that they need to switch strategy to a more moderate Republican. It will likely be Haley or somebody from outside Washington. I think there's too much ill will towards Romney for his impeachment vote of Trump and the fact he lost a presidential election already so I doubt he even runs.
If it's a narrow defeat then Republicans will just blame it as bad timing with covid and a Trump like figure is more likely to win. MAGA politicians and hardline conservatives will likely run and draw the most support (Donald Trump Jr., Gaetz, Krenshaw, Jordan, Cruz, Cotton, etc.). It's a long way off though so who knows.
