Every four years, millions of Americans wonder why they choose their presidents through the Electoral College, an arcane institution that permits the loser of the popular vote to become president and narrows campaigns to swing states.

Several of these efforts—one as recently as 1970—came very close to winning approval. Yet this controversial system remains.
