Lol, no you're not going to pass a constitutional amendment that effectively removes all the voting power of everyone outside the major coastal areas. You couldn't even pass the ERA, and that one was actually the pre-2010s version of feminism, where actual equality was being advocated (and which, overall, I'd have supported, short of forcing women to be draft-eligible).
And the main reason why you'll never pass that, or any other legislation you promise, is that Democrats lost their ability to convince anyone else. They threw it in the trash and replaced it with screaming "__ist and __phobe" at literally half the country anytime they step out of line of the latest Official Beliefs, which keep getting revised.
