Missouri’s top election official has rejected a citizens’ petition seeking a statewide referendum on new congressional districts backed by President Donald Trump. Supporters of the referendum had submitted hundreds of thousands of petition signatures in a bid to force a November election on a new U.S. House map approved by the Republican-led state Legislature. But Republican Secretary of State Denny Hoskins asserted Tuesday that the petition is void because congressional redistricting plans cannot be subject to voter referendums. The number of petition signatures submitted doesn’t matter, Hoskins said, because “challenging a congressional map is unconstitutional under Missouri law.” Republicans already hold six of Missouri’s eight congressional seats and hope to gain another under the new map.
