Aug. 14, 1946:

McCarthy for Senator.

Joseph McCarthy, a circuit court judge and World War II veteran, upsets Sen. Robert La Follette Jr. in the Wisconsin Republican Senatorial primary.

McCarthy will win the seat in November. Within four years, he will become nationally known for his crusade against Communists, real and imagined, in the U.S. government.

He will be "condemned" (censured) by the Senate in 1954, and will serve in that body until his death in 1957.
