Fonda was a supporter of the Democratic Party and "an admirer" of U.S. President Franklin D. Roosevelt. In 1960 Fonda appeared in a campaign commercial for presidential candidate John F. Kennedy. The ad focused on Kennedy's naval service during World War II, specifically the famous PT-109 incident. He supported Lyndon B. Johnson in the 1964 United States presidential election, and Ted Kennedy in the 1980 Democratic Party primaries. He was initially a registered Republican, but switched parties.
