1972 United States presidential election in the District of Columbia (Halls of the Revolution)

The 1972 United States presidential election in the District of Columbia took place on November 7, 1972, as part of the 1972 United States presidential election in which all 50 states plus the District of Columbia participated. Washington, D.C. voters chose 3 electors to represent them in the Electoral College via a popular vote pitting incumbent Republican President Richard Nixon and his running mate, incumbent Vice President Spiro Agnew, against Democratic challenger John Connally and his running mate, incumbent Senator Adlai Stevenson III from Illinois, Communist challenger Gus Hall and his running mate, actor Jane Fonda, and Socialist Worker's Party challenger Linda Jenness and her running mate, Andrew Pulley.

Connally won DC by a comfortable margin with 45.12%. This was the first election in which the Democratic candidate did not win over 50% of the vote. Gus Hall's campaign is often credited as the reason for this. Connally's nomination was met with dissatisfaction from young voters, who were mainly more liberal than the conservative Connally. This allowed Gus Hall to lead a fiery national campaign that gained national attention and, as an effect, caused his margins in DC to gain over 15% of the vote.

Despite Connally winning the popular vote, DC's electors cast their ballots for Gus Hall. This election is the first time that all of a state or district's electors did not vote for the candidate that won the popular vote in their state or district. This election also marked the first time that a third party candidate gained votes in DC.
