They'd have to prove they are a US citizen and not some mail order bride from a foreign country... which some of these maga people may be prone to do.

But yeah, it may well work against the maga folks who can't afford to buy passports or don't have the wherewithal to gather up all the certified documents they would need to prove who they are, even for the men.

I don't think they really think these things through. But who cares? By that time, we wouldn't have free or fair elections anyway, so it would be a moot point. They'll just have to get used to being peasants like in the "golden age" of yore... for the royal or 'aristocrat' class anyway.
