Proponents, however, argue new maps for the 2022 elections will more accurately reflect the partisan breakdown of Missouri, where statewide elections are often decided by a margin of fewer than 10 percentage points.

Sen. Bill Eigel, R-Weldon Spring, has introduced a resolution that would allow voters to reexamine redistricting this fall.

In Clean Missouri, the redistricting provision was one of five proposed ethics changes; voters approved the package with 62% of the vote.

"The redistricting was hidden among a number of other proposals in Clean Missouri," Eigel said.

Eigel's plan and others would place redistricting powers in the hands of a bipartisan commission, the process that was in place for the current state legislative maps.

"The system we had prior to Clean Missouri, you had a process that had the input from folks from across the political spectrum," Eigel said. "We went from a good system to a very unfair system."

(Under the new plan, the bipartisan commission will still exist, and can make changes to the demographer's map if 70% of its members go along with an alteration.)
