And who or what exactly is going to stop him?
When no one (who is in a position to enforce) cares what is legal or constitutional, he can do anything he wants. Just look at the current state of the US and tell me anyone in any power or authority cares. Do you really think “third term” is where they’ll draw the line? I’d put every dollar I have that is not actually about not carrying, but that this is the desired outcome, to enrich themselves.
I only see one way to stop him, and it’s certainly not by law or votes.

A generation ago, Iran was not like this. Islam itself does not require any of this. An important part if Islam is that the Qur’an cannot be translated, so it is in a form of Arabic few people can really understand. People must depend on the mullahs to tell them what it says. (Which was once also what Christians said about the Latin Bible, though that makes even less sense than the Qur’an because the Bible was translated into Latin.) This is anti-women conservatives using the guise of religion to push their hatred on women and control the population as a whole. As you say, Christianity was once used in the same way, but it still is now, isn’t it?
In the US, abortion is a bogeyman used to threaten women from getting healthcare (even to the point of death), and monitor and control their movements. It’s being done under the guide of “Christianity”. “Christianity” is used against people of different races (because they can’t really be Christian if they’re not white), actually other religions, sexuality, and gender. Yet, how much did Christ ever talk about these things?
