Authoritarian populism isn't tied to Trump, and in a country with multiple political parties, he could start a viable alternative to MAGA by continuing their methods and program, but attacking Trump personally and blaming all issues on Trump's extreme corruption and obvious mental disability.
Basically try to run on "MAGA but without the personality cult of Trump and the incompetent sycophants he put into positions the American people need to be staffed by professionals".
For whatever reason, he is deathly afraid of naming the orange nigger though. I don't know what he thinks, perhaps he wants to flex his muscles to regain power under Trump: "I am strong enough to cause you problems, so bring me into the fold again?"
Or maybe he's just flailing around like a retard. That's always a credible possibility for these people.
Trump: America should be like Russia.
Musk: America should be like China.

Pick your future.
