Missouri is the third American state to take up mid-decade redistricting in an emerging national battle for partisan advantage ahead of 2026 midterm elections.

Segregation line between Black, white residents

Trump is trying to stave off a historic trend in which the president's party typically loses seats in midterm elections.

Republicans currently hold six of Missouri's eight US House seats.

The revised map passed the state House earlier this week as the focal point of a special session called by Kehoe.

Missouri's revised map targets a seat held by Democratic US Representative Emanuel Cleaver by shaving off portions of his Kansas City district and stretching the rest of it into Republican-heavy rural areas.

The plan reduces the number of Black and minority residents in Cleaver's district, partly by creating a dividing line along a street that Cleaver said had been a historical segregation line between Black and white residents.
