I suspect if they wanted him they'd find ways to qualify him. He's not actually political material in terms of skills or the connections needed to rise to the Governor's office. He's charismatic for a certain audience and that's meaningful in Idaho but not enough to own the office without a great deal of support from the party.
I see him as a threat to the GOP and to the discussion of issues that an election process tends to be. Despite the hype of his past he's actually a grandstander who's getting a ride in the press until someone who's got background in the party steps up and asks the harder questions.
He's got no useful answers to COVID which is going to be a serious issue by the primary season. Trump isn't in love with him either. He's a party of one pretending to represent the broader populace in Idaho. He has no plans to put kids in school, to pave roads, or save the Idaho economy.
I think that empty promise will loom very large by the time people have to make up their minds. I don't know who they'll chose but I don't think Ammon will stand quite so tall by the time that choice is made.
