The 1984 United States presidential election in the District of Columbia was held on November 6, 1984 as part of the 1984 United States presidential election. Democratic candidate Walter Mondale won D.C. with 85% of the vote, giving him three electoral votes. In the general election, he only carried a total of 13 electoral votes, the other 10 coming from his home state of Minnesota.
