Joe Must Go Yellow

Black text on a yellow background.

Joseph McCarthy was a Republican Senator from Wisconsin from 1947 to 1957. During the Cold War with the Soviet Union when the U.S. feared the spread of communism, McCarthy became known for his smear tactics against Americans who were under suspicion of communist ties. His practice of making allegations against people without evidence has become known as "McCarthyism".

"Joe Must Go" was a movement to recall Senator McCarthy in the early 1950s. It was financed by a book of the same title by Leroy Gore. The movement was initiated because McCarthy was seen as disrespectful of Wisconsin's General Ralph Wise Zwicker whom he was investigating, undermining President Eisenhower's authority, and ignoring the dilemma that dairy farmers were facing with price-slashing surpluses.
