No, it's unconstitutional which states: "...To exercise exclusive Legislation in all Cases whatsoever, over such District (not exceeding ten Miles square) as may, by Cession of particular States, and the Acceptance of Congress, become the Seat of the Government of the United States, and to exercise like Authority over all Places purchased by the Consent of the Legislature of the State in which the Same ......"
In other words, the federal government should never be subservient to a state. Granting statehood to DC would place the safety and security of the President and Congress in the hands of whoever is in control of DC if turned into a state.. The founding fathers were specifically concerned about exactly that when they decided that the federal capital would not be located in any state but remain neutral in matters of the states.
Also, D.C. is a CITY, not a state. It has a mayor, but no governor. The mayor has control of what is lawful in that city, just like in other cities. Cities do not have representatives in Congress. The mayor of D.C. wants statehood and wants 2 MORE representatives in Congress. Doesn't work that way either according to the Constitution. Each state gets 2 Senators, no more. They cannot have statehood unless the states of MD and VA take back their land area and allow D.C. to become a blended state by claim.
Article I, section 3, of the Constitution was modified by the 17th amendment.
"The Senate of the United States shall be composed of two Senators from each State, elected by the people thereof, for six years; and each Senator shall have one vote. The electors in each State shall have the qualifications requisite for electors of the most numerous branch of the State legislatures."
