A 1978 proposed constitutional amendment to grant Washington, D.C., statehood failed, and in 1993 the U.S. House of Representatives voted against legislation to make the nation’s capital a state. In 2016, D.C. residents approved an advisory referendum supporting statehood. Earlier this year, the House included a nonbinding endorsement of statehood for D.C. among various good-governance proposals. A separate bill proposed by Washington Del. Eleanor Holmes Norton to grant the district statehood will be taken up by a House committee later this year. Even if successful in the House, the bill has little chance of being considered by the Republican-led Senate.

No major subgroups of Americans voice support for D.C. statehood. However, support is higher among left-leaning political groups than right-leaning ones. Self-described liberals (40%) and Democrats (39%) are among the groups showing higher support. Republicans (15%) and conservatives (14%) are among the subgroups least supportive. Thirty percent of independents approve of making D.C. a separate state.
