The latest in Iowa

Oct. 7, 2021

On Oct. 5, the Iowa Senate, in a 32-18 vote, rejected the nonpartisan Legislative Services Agency’s first proposal for a new congressional map. The failed map would have likely netted Democrats one seat, as it made the currently Republican-held 1st District noticeably bluer (but the 2nd District got redder as a trade-off). The 3rd District (a swing seat currently held by Democratic Rep. Cindy Axne) and 4th District (solidly Republican) would have roughly retained their current leans.

This rejection sends the LSA back to the drawing board. The agency now has 35 days to submit a new map to lawmakers. The LSA said it would submit the map by Oct. 21, giving themselves 16 days. The legislature has to wait seven days before they can vote on the plan, so the soonest they can convene for a vote is Oct. 28.

If the second map is also rejected, lawmakers can make amendments to the LSA’s third proposal — something they can’t do with the first two proposals.
