See also: How vacancies are filled in state legislatures

If there is a vacancy in the Iowa General Assembly, the vacant seat must be filled by a special election. The governor of Iowa is required within five days of a vacancy in the General Assembly to call for a special election. If the vacancy happens in session or within 45 days of the session convening, the governor must call for an election as soon as possible with at least an 18-day notice. All other special elections require a 40-day notice as long the election does not happen on the same day as a school election within the district.^[5]

2016 pivot county

See also: Pivot Counties and Legislative districts intersecting with Pivot Counties

This district was one of 710 state legislative districts that, based on boundaries adopted after the 2010 census, intersected with one or more Pivot Counties. These 206 Pivot Counties voted for Donald Trump (R) in 2016 after voting for Barack Obama (D) in 2008 and 2012.

The 206 Pivot Counties were located in 34 states. Iowa, with 31, had the most such counties. At that time, the partisan makeup of state legislative districts intersecting with Pivot Counties was slightly more Republican than the overall partisan makeup of state legislatures throughout the country.^[6]

Redistricting

2020 redistricting cycle

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.^[7] 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:^[8]

one member selected by the majority leader of the Iowa State Senate
one member selected by the majority leader of the Iowa House of Representatives
one member selected by the minority leader of the Iowa State Senate
one member selected by the minority leader of the Iowa House of Representatives
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)."^[8]

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.^[8]

State law establishes the following criteria for both congressional and state legislative districts:^[8]

Districts must be "convenient and contiguous."
Districts must "preserve the integrity of political subdivisions like counties and cities."
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."^[8]
