I’m just curious, what compels you to oppose the 19th. Is it that you consider women not mature enough to vote, or too emotional to vote, or not smart enough, or what? And yes, I do realize that had only women voted for President in 2000, Al Gore would have won solidly.
Patterns of women's voting are different from those of men. Women for whatever reasons seem far more inclined to vote for candidates who would use the Constitution as toilet paper. While I don't know that forbidding women from voting would be the proper solution to this, the voting patterns would seem to be a basis for concern.
BTW, I think a major key to restoring the republic would be for the Supreme Court to acknowledge that states are only required to have one legislative body elected proportionally by the population, and that in bicameral legislatures it is entirely proper to have one body elected via some other means. Clearly the Founding Fathers would have considered such a split appropriate.
