Davis accepted the Communist Party USA's nomination for vice president, as Gus Hall's running mate, in 1980 and in 1984. They received less than 0.02% of the vote in 1980. She left the party in 1991, founding the Committees of Correspondence for Democracy and Socialism. Her group broke from the Communist Party USA because of the latter's support of the 1991 Soviet coup d'état attempt after the fall of the Soviet Union and tearing down of the Berlin Wall. Davis said that she and others who had "circulated a petition about the need for democratization of the structures of governance of the party" were not allowed to run for national office and thus "in a sense [...] invited to leave". In 2014, she said she continues to have a relationship with the CPUSA but has not rejoined. In the 21st century, Davis has supported the Democratic Party in presidential elections, endorsing Barack Obama, Hillary Clinton, and Joe Biden.
