In a way, that's how the Electoral College was set up from the get go. To prevent the tyranny of urban areas (states) over the rural ones. Look at Illinois in their last Governor's race where the Democrat "won" narrowly statewide. The Democrat won Cook County and just 3 other scattered counties (1 urban, 2 rural) while the Republican took everything else in a landslide. Nevermind that the race was rife with fraud, one should look at such a map and it's a no-brainer who should prevail:
(Note the proper color scheme of Red=Democrat and Blue=Republican)
So lets say you had to explain to a black voter in Chicago why the vote of a white guy in Mattoon should count 2 or 3 or even 4 times as much as their vote?
What would your argument to them be?
