Washington, D.C., has three electoral votes. However, until the 23rd Amendment of the United States Constitution was ratified in 1961, Washington, D.C., residents did not have the right to vote in presidential elections, being governed, as per the Constitution, solely by Congress.
The 23rd Amendment granted Washington, D.C., the same number of electoral votes as Wyoming, as the least populated state. Their votes are among the 538 total national votes, of which a candidate needs at least 270, or more than half, to win the presidency.
Washington, D.C., residents first voted in a presidential election during 1964, from which time the district's electoral votes have always been for the Democratic Party.
