U.S. democracy is in existential crisis.
The country already suffers from unrepresentative winner-take-all, single-seat-district legislative elections, a two-party duopoly, partisan gerrymandering, the corrupting influence of big money in politics, and an Electoral College and US Senate that give vastly outsized influence to some voters over others. In the case of the Electoral College, it can also prevent the presidential candidate receiving the most votes from being elected.
