We would need a Constitutional Amendment to allow states to restrict the vote, since the 14th, 19th and 24th(?) Amendments pretty much took care of restricting it.
Restricting the vote to real property owners make sense, since they’re typically paying the whole enchilada (income, sales, and property taxes, in addition to various excises).
And we could even reinstate that restriction and be *gag* gender-neutral about it. If you rent an apartment or own a house you get to vote, so long as you’re not on any kind of state or federal assistance. Simple as that.
Now we also desperately need to raise the voting age by at least 5 years with an exception for members of the armed services. But I can tell you right now that is gonna be one hell of an uphill battle because clueless college brats are one of the core Democrat voting classes. They will NOT stand idly by and lose them.
