Nonsense?
Following what desantis swore an oath to do is what a good leader woukd do. Instead he is trying to please himself, and just using those he swore to be governor for. If he cannot keep his word/oath he is not worthy of any job representing people in any capacity. (Just because plenty of others doing it too doesnt make it ok)
Who’s going to enforce this law in the instance you are citing?
A reasonable statutory construction permits the man to run. If he decides to run, he will rely on that construction, or another reasonable construction, provided to him in the form of a lawyer’s legal opinion. In such a circumstance, he won’t look back, and it is unlikely that anyone who believes in the narrow negative construction will even have/demonstrate standing, much less win a legal battle. We already have federal standards for who can run and hold the office of POTUS, as spelled out in the Constitution. No need for a state to seek to add to those requirements.
