The latest in Iowa

Nov. 5, 2021

Iowa Gov. Kim Reynolds has signed the Hawkeye State’s new congressional map into law, cementing the state’s new political lines for the next decade. After the map was approved by lawmakers, Reynolds said in a statement on Oct. 28 that she believes the new map “fairly and accurately represent the citizens of Iowa.”

The new map, drawn by the nonpartisan Legislative Services Agency, creates one solidly Republican seat, one competitive Republican seat and two highly competitive seats. The map is slightly less competitive than the old one, with the number of districts whose partisan leans are between R+5 and D+5 going from three out of four in the old map to two out of four in the new map. The map also makes Iowa’s new 2nd District (where most of the old 1st District was located) 2 percentage points safer for the GOP, although the 3rd and 4th districts would have roughly the same partisan leans as the old map.

Who controls redistricting in Iowa right now?
Republicans fully control the congressional redistricting process. New maps are drawn by a bipartisan commission made up of citizens, but the Republican state legislature can modify or reject the commission's proposals. The final map must be passed by the state legislature and signed into law by the Republican governor.
