Missouri voters decide congressional races and five ballot measures Tuesday

Supreme Court rulings leave November districts unchanged from 2022 and 2024

Missouri voters will choose members of the U.S. House, a state auditor and state legislators, and decide five statewide ballot measures in Tuesday’s election. Polls close at 7 p.m. local time, or 8 p.m. Eastern, according to the Associated Press. The statewide measures include Proposition A on congressional redistricting and Amendment 3 on abortion and gender transition for minors.

The election follows a long-running legal fight over the mid-decade congressional redistricting plan that Missouri Republicans adopted as part of President Donald Trump’s push to redraw congressional district boundaries ahead of schedule to boost the party’s prospects of holding its fragile House majority, according to the AP. The U.S. Supreme Court settled the dispute three times in September.

The court’s decisions mean Tuesday’s voters might cast ballots in the same districts they used in the 2022 and 2024 elections, even though they may have voted in differently shaped districts in the Aug. 4 primary.

Missouri voters cast about 2.1 million ballots in the state’s 2022 election for U.S. Senate, according to the AP, and early in-person and mail ballots made up about 23% of the vote in that contest. The AP’s advance vote tracker carries the latest advance vote totals for Missouri.

Counties overwhelmingly release all or almost all early in-person and Election Day results at the start of the night, and the vast majority of counties also release mail voting results in the first report, according to the AP. The first vote reports of the night tend to be a mix of all vote types.

In Missouri’s 2024 general election, the AP first reported results at 8:18 p.m. Eastern, 18 minutes after polls closed. The count reached the halfway mark at 10:30 p.m. Eastern, and 90% of total votes were counted by 12:30 a.m. Eastern.

The AP will provide vote results and declare winners in contested races for U.S. House, state auditor, state Senate, state House and the statewide ballot measures. The news organization does not make projections and declares a winner only when it determines “there is no scenario that would allow a trailing candidate to close the gap.”

If a race remains uncalled, the AP says it will continue to cover newsworthy developments, such as candidate concessions or declarations of victory, while making clear that it has not declared a winner and explaining why.

Missouri does not have automatic recounts. Candidates for federal, judicial and state offices, including the state Legislature, may request a recount if the margin is less than 0.5% of the vote. Candidates for local offices may request one if the margin is less than 1%. A court may also order a recount as part of an election contest proceeding. The AP may declare a winner in a race subject to a recount if it determines the lead is too large for a recount or legal challenge to change the outcome.
