Voting rights of citizens in the District of Columbia differ fr...wikipedia - 04 Nov 2020
Voting rights of citizens in the District of Columbia differ from the rights of citizens in each of the 50 U.S. states. The Constitution grants each state voting representation in both houses of the United States Congress. As the federal capital, the District of Columbia is a special federal district, not a state, and therefore does not have voting representation in Congress. The Constitution grants Congress exclusive jurisdiction over the District in "all cases whatsoever".
