If I could travel back in time to 1791 and tell the founding fathers to do something, I'd...

[Amenhotep Bakari-Sellers]

Tell George Washington-Ben Franklin(who were conservatives at the time, who made the constitution, but were Whigs, not Tories-fighting slavery): The EC college and Senate should be reallocated by proportional voting with EC college and by direct election of senators instead of state legislatures. As a result, the need for the protection against females and slaves from influencing elections, would be brought down by the 13th and 20th Amendments. Both proposed by a secular Republican Lincoln and a centrist Democrat named Wilson.

I presume you meant the 19th rather than the 20th amendment in your ramble, since the 19th dealt with women's suffrage while the 20th just changed when Congressional and Presidential terms began and clarified what happens when there is no majority in the EC.

Considering that Wilson was staunchly opposed to women's suffrage until well into the Great War, I can't see how anyone can say he proposed it. He wasn't a bitter-ender on the subject, but he wasn't a primary mover either.
