Ronald Reagan was an actor and president of the Screen Actors Guild starting in 1947. In the 1960s he became a conservative Republican politician. He served as Governor of California from 1967-1975 and was elected president in 1980. This anti-Reagan button comes from the 1970s when Reagan was Governor of California. The slogan "Ronald Reagan is a Lesbian" comes from a sign used in the play Hair, which debuted on Broadway in 1968. This sign was either used in protest scenes or hung on the set with other signs to show the political and cultural turmoil of the 1960s. Hair showed the hippie and counterculture movements, which Reagan was critical of. U.C. Berkeley was an early center of the counterculture and protest movements portrayed in Hair, and Reagan was especially critical of the protest on campus in the late 1960s, when he was Governor of California.
