Going to get down voted for this, but I honestly think Minnesota has the right of it. The GOP is a private entity and can run whoever they want in their primaries.
14A has nothing to say about how parties select their candidates, and if they want to select someone who isn’t qualified that’s their problem.
Also, if Trump fails to win the GOP nomination, someone really needs to seed the idea that they should all do write in votes for Trump instead of whoever the GOP would nominate instead. Show the GOP they shouldn’t back down and show the Dems they can’t stop the Trump Train. Also, you know, splitting the GOP vote to make an easier Dem win, but sshhh about that last part.
Primaries use public voting infrastructure, at least in my state, so I can see the argument that courts can decide who is a legal primary candidate.
The risk is what the GOP is threatening to do in Colorado. If Trump isn’t allowed on the public voting infrastructure, they’ll just caucus instead.
In which case, it’s likely that independents won’t be allowed to participate.
So for primaries, it’s likely to have the opposite effect, more likely for a Trump candidacy, by stirring up the base and locking out potential moderate voters.
For general election, Maine and Colorado don’t practically matter, they were never going to go to trump anyway. So for these two states, it’s ammunition for a persecution complex without good result. For it to be a good strategic win, it would have to be some states that Trump actually has a chance of winning.

They have every right to. Again, because a primary isn’t an election for office, it’s a private entity (in this case the GOP) being allowed to borrow public infrastructure to help them decide who they want to back for the actual election.
Same reason super delegates for the Dems weren’t illegal, even if they were in bad faith.
