1968 Misunderstood

Levitsky and Ziblatt assert that the political parties usefully blocked George Wallace from mounting a seriously threatening presidential campaign in 1968, page 47. But they neglect to point out that Wallace cost Democratic candidate Hubert Humphrey the chance to carry previously Democratic states in the Deep South and some critical northern states where Wallace captured a large share of blue-collar voters. The election was very close. Wallace arguably cost Humphrey the election. The presidential selection system allowed Wallace to capture all electors from certain states. It always invites spoiler third-party candidates, of which Wallace and Ralph Nader are two notorious examples.
