What Redistricting Looks Like In Every State

An updating tracker of proposed congressional maps — and whether they might benefit Democrats or Republicans in the 2022 midterms and beyond.

Who controls redistricting in Iowa in 2021?
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.

The latest in Iowa

Sept. 16, 2021

On Sept. 16, Iowa’s nonpartisan Legislative Services Agency released its first proposal for the Hawkeye State’s new congressional map. The map would likely net Democrats one seat, as it makes the currently Republican-held 1st District noticeably bluer (but the 2nd District gets redder as a trade-off). The 3rd District (a swing seat currently held by Democratic Rep. Cindy Axne) and 4th District (solidly Republican) would roughly retain their current leans.

However, it remains to be seen whether this map (or one like it) will actually become law. While Iowa has adopted the LSA’s congressional maps in every redistricting cycle since the adoption of the current redistricting process, this is the first cycle since then that Republicans have enjoyed full control of state government. And if they want, they can reject the LSA’s plans and draw their own. If they go that route, not only will Democrats likely not gain a seat in Iowa, but Axne will probably be made more vulnerable as well.
