Yeah, my reading of Article 14 sec 3 is simply put he cant hold office. Doesn't mention anything about elections or what to do if he wins an election (unless congress votes 2/3 to allow him to hold office). Up until that point it is likely a state matter for how they handle their elections, especially when it does not involve the general/federal elections.

I'd say it likely falls under whatever "Obama wasn't born in America, he can't be president" if that statement were ever actually true. I don't know the legal precedence though for people running for office that aren't legally qualified to hold the office.

I'm sure if he actually wins the primary for the GOP ticket, it will end up at the supreme court. Honestly this is a golden opportunity for the GOP to rid themselves of the burden that is Trump, and they would fully get to blame the Supreme Court and democrats, and scream about it til the end of time for their electorate; many of them hate having to cow-tow to Trump, and even regret missing the opportunity to impeach him and be done with him. Y'all get a second chance, and this time very little backlash for yourselves, unlike if you'd voted to impeach after Jan 6th.
