Huh?
The Founders also would have known that plurality elections (whoever gets the most votes wins) tend to generate just two parties, while proportional elections (vote shares in multi-winner districts translate into seat shares) tend to generate multiple parties, with the district size and threshold percentages shaping the number.
So called "proportional voting" is a thinly disguised form of mob rule, under which, among other things, the Electoral College would be eliminated.
Quite intentionally Im sure. You know a journalist is up to something any time they talk about “democracy” as though that is a positive thing.
