I just had a thought, which, after reflecting, is not at all far-fetched.
It is 2026. The GOP has the trifecta. Trump is unstable and has had a few nights in a hospital. Sen. Rand Paul introduces a bill in the Senate, with Rep. Greene concurring in a House bill, to strike from the Constitution the requirement to have been born in the U.S. in order to be President.
They install Elon Musk as President, who, with his billions, can easily outspend and out-tech any challenger.
The Constitutional change may not be as rapid as that; it may take until 2032. But I do think it is more than possible. I believe it to be likely. Republicans long ago gave up on the rules-based order.
