citywide vote on whether the District should become the 51st state. This was followed by the release of a proposed state constitution. This constitution would make the mayor of the District of Columbia the governor of the proposed state, while the members of the City Council would make up the proposed House of Delegates. Despite requests for a different name, the proposed state constitution refers to the District as "New Columbia." However, the Council of the District of Columbia passed legislation making the proposed name "State of Washington, D.C." Under this proposed name "D.C." stands for "Douglass Commonwealth," a reference to the historic abolitionist Frederick Douglass. District residents voted overwhelmingly in favor of statehood, in an advisory referendum, but statehood legislation is unlikely to be enacted. On June 26, 2020, during the 116th Congress, the House of Representatives passed a bill to grant statehood to the District () by a vote of 232–180. H.R. 51 never received a vote in the Senate during the 116th Congress. The Office of Management and Budget said President Donald Trump's advisors would have recommended he veto H.R. 51 if it was passed by Congress. H.R. 51 was introduced in the 117th Congress. On January 26, 2021, Tom Carper of Delaware also introduced a similar bill, S. 51, "A bill to provide for the admission of the State of Washington, D.C. into the Union" into the United States Senate with a record 38 co-sponsors. On April 14, the United States House Committee on Oversight and Reform voted to pass H.R. 51, paving the way for the whole House to vote on it. The House passed that bill on April 22 with a vote of 216–208. On April 30, Democratic senator Joe Manchin came out against both H.R. 51 and S. 51, effectively dooming their passage. Comparison with other national capitals Other countries with federal systems similar to the U.S. either extend full voting rights to residents of the federal capital, comparable to those of a constituent state, or have established their capital within a larger sub-national jurisdiction. Federal districts and territories In the National Congress of Argentina, the Autonomous City of Buenos Aires has 25 seats in the Chamber of Deputies as well as three in the Senate, the same as a province. In the Parliament of Australia, the Australian Capital Territory (ACT) has seats in both the House of Representatives and Senate. However, it
