District of Columbia residents deserve the same voting rights and representation in Congress as any other American living in one of the 50 states regardless of what the Constitution says. Denying D.C. residents the right to have senators and representatives in Congress is a violation of their democratic rights. As long as D.C. residents pay federal taxes and are subject to federal laws, they should get to enjoy the full benefits of statehood and representation in Congress.
The U.S. Constitution explicitly made D.C. a district, not a state. If D.C. residents want full representation in Congress they can move to nearby Maryland or Virginia & get it. Alternatively, Congress should pass legislation treating D.C. residents as Maryland residents for the purposes of congressional representation, or just give parts of D.C. that aren't federal buildings back to Maryland. Granting D.C. statehood is a ploy by Democrats because they expect they would win the two Senate seats & the House seat.
