In the 1972 United States presidential election, Spock was the People's Party candidate with a platform that called for free medical care; the repeal of "victimless crime" laws, including the legalization of abortion, homosexuality, and cannabis; a guaranteed minimum income for families; and the immediate withdrawal of all American troops from foreign countries. In the 1970s and 1980s, Spock demonstrated and gave lectures against nuclear weapons and cuts in social welfare programs.[citation needed]
