I'm amused at Trumpkins going "You should read history and learn why we have an Electoral College". They are so proud at having read something on the internet!
But in fact, the Electoral College had two functions:
1. Let a small group of elected white men talk among themselves to decide who shall be president. It has never had that debate (except possibly when Aaron Burr tried, and they rejected him).
2. Let slave states have more power. 1000 voters in a free state would have the same electoral power as 300 voters in a slave state who between them owner 2700 or so slaves. (The slaves, of course, didn't vote).
So which purpose are they arguing for?
Oh, they *say* its so that small rural states have a voice. But they *know* that's false. No-one ever seriously campaigns in a non-battleground state, big or small. Rural voters in Montana, Idaho, the Dakota ... or eastern Washington ... might as well stay home because their votes are never courted.
A popular vote system means a voter in a tiny town has the same voice as a voter in a big city. And the way modern campaigns work, it is just as easy to reach that small town voter as the big city voter. Advertising rates are per-viewer, not per-square-mile.
