LINCOLN, Neb. (AP) — A ballot measure that would let 18-year-olds serve in public office in Nebraska has won first-round approval.

Lawmakers voted 27-11 on Monday to advance the measure, which would apply to the offices of governor, lieutenant governor, the Legislature and the Supreme Court.

Two more legislative votes are required before the measure could appear on the November ballot. Nebraska imposes an age minimum of 21 for state senators and 30 to serve as a governor, lieutenant governor or Supreme Court justice.

Sen. Tyson Larson of O’Neill says voters should be able to choose anyone who has reached the federal voting age and is otherwise qualified to serve.

Some senators opposed the measure, saying it could result in governors and justices whose brains haven’t fully developed.
