Redistricting

2020-2021

See also: Redistricting in Iowa after the 2020 census

On November 4, 2021, Iowa Gov. Kim Reynolds (R) signed new congressional and state legislative maps into law after the state's Legislative Services Agency had proposed them on October 21, 2021. The Iowa legislature approved the maps on October 28, 2021, by a vote of 48-1 in the state Senate and 93-2 in the state House. The legislature could only vote to approve or reject the maps and could not make any amendments. These maps took effect for Iowa's 2022 congressional and legislative elections.

How does redistricting in Iowa work? The Legislative Services Agency prepares redistricting plans for approval by the Iowa State Legislature. According to All About Redistricting, the Legislative Services Agency (LSA) consists of "civil servants committed to nonpartisanship and otherwise charged with tasks like legal and fiscal analysis of state legislation and state government oversight." The LSA is assisted by a commission, which consists of the following members:

1. one member selected by the majority leader of the Iowa State Senate
2. one member selected by the majority leader of the Iowa House of Representatives
3. one member selected by the minority leader of the Iowa State Senate
4. one member selected by the minority leader of the Iowa House of Representatives
5. one member selected by the first four members

The members of this commission cannot "hold partisan public office or an office in a political party, and none may be a relative or employee of a federal or state legislator (or the legislature as a whole)."

Working with this commission, the LSA drafts congressional and state legislative district lines. The maps are presented as a single bill to the state legislature, which may approve or reject the bill without altering it (the legislature can provide feedback). If the legislature rejects the plan, the LSA must draft a second proposal. If the legislature rejects the second proposal, the LSA must draft a third, and final, set of maps. If the legislature rejects this plan, it may then approve its own maps. Since the implementation of this process in 1980, the state legislature has never chosen not to approve an LSA proposal. Redistricting plans are also subject to gubernatorial veto. In addition, the legislature may repeal or revise the maps at any time, though it has never done so.

State law establishes the following criteria for both congressional and state legislative districts:

1. Districts must be "convenient and contiguous."
2. Districts must "preserve the integrity of political subdivisions like counties and cities."
3. Districts must "to the extent consistent with other requirements, [be] reasonably compact–defined in terms of regular polygons, comparisons of length and width, and overall boundary perimeter."

In addition, state House districts are required to be contained within state Senate districts "where possible, and where not in conflict with the criteria above." It is explicit in state law that district lines cannot be drawn "to favor a political party, incumbent, or other person or group."
