founding fathers were way smarter than we could ever hope to be
they never wanted the special interests of any one demographic to carry the national agenda. If we went with a popular vote, the votes would be more meaningless than ever. You see, all one party would need to do is get out the vote in NYC, Philly, DC, Chicago, St Louis, Miami, Atlanta, Boston, Detroit, LA, Houston and nobody else would matter. And then you do things to buy those votes and put all your people in those cities, and you're set for life. People in a few isolated areas vote for their own special interest and baddafuckingbing, you destroy the republic
To make everyone's vote more meaningful, you actually should eliminate winner take all states. Make every county matter, make every state important, make them have to campaign in all 50 states.
I'm suggesting that we make every county important. A popular vote would make only a few large cities important.
