George Wallace
George Wallace had become famous as the segregationist governor who stood “in the schoolhouse door” to prevent black students from enrolling at the University of Alabama in 1963 (though after being confronted by federal marshals, he stepped aside). In 1968, he campaigned for the Democratic presidential nomination on a populist “law and order” platform that appealed to many blue-collar voters concerned about antiwar protests, urban riots, and the rise of the counterculture.
