All seven Iowa legislators who faced competition for their party’s nominations prevailed in the June 4 elections. The outcome was a reversion to normal following a tumultuous 2022 cycle, in which six Iowa House Republicans lost their primaries. Two years ago, Iowa’s new political map forced three pairs of House members to face off against each other, and Governor Kim Reynolds endorsed challengers against several more GOP lawmakers who had opposed her “school choice” plan.

Crucially, Reynolds did not endorse any 2024 candidates running against incumbents. On the contrary, she backed one of the incumbents in a tough primary.

In addition, property rights proved to be a less potent issue here than in South Dakota, where fourteen Republican lawmakers lost to primary challengers on June 4.

Although Iowa saw no upsets, several of this year’s legislative races revealed that Republicans could be vulnerable to candidates from the right. The two challengers who came closest to knocking off incumbents were both vocal opponents of using eminent domain to build CO2 pipelines.

This post covers the primaries from the narrowest winning margin for the incumbent to the most comfortable victory.

UPDATE: I’ve added unofficial results for each race.

Iowa Democrats have more competitive state legislative primaries in 2022 than in a typical election cycle. That’s partly because quite a few House and Senate members are retiring, and partly because the redistricting plan adopted in 2021 created some legislative districts with no incumbents.

In most of the races discussed below, the winner of the primary is very likely to prevail in November. However, a few of the districts could be targeted by one or both parties in the general election.

All data on past election performance in these districts comes from the Iowa House and Senate maps Josh Hughes created in Dave’s Redistricting App. Fundraising numbers are taken from the Iowa Ethics and Campaign Disclosure Board’s database.

This post is not an exhaustive account of all contested Democratic primaries for state legislative offices. You can find the full primary candidate list here.

Bleeding Heartland’s legislative campaign coverage has tended to focus on battleground districts. But next year, Democrats will have more open seats than usual in solid blue Iowa House or Senate districts.

Although those races won’t affect control of either legislative chamber, they could be important for the future of the Iowa Democratic Party. Lawmakers from safe seats may rise to leadership positions at the statehouse or run for higher office someday. So I intend to keep a close eye on contested primaries in some districts that won’t be competitive in November.

One such race is shaping up in Iowa House district 89, where long-serving State Representative Mary Mascher announced last month that she will not seek re-election. Three Democrats are actively campaigning here. The newest contender, Tony Currin, will take several advantages into the primary.

Voters in Iowa’s bluest city will elect at least two new state lawmakers next year. State Senator Joe Bolkcom announced on November 4 that he will not seek another term in 2022. First elected in 1998, Bolkcom said in a message to constituents and supporters that it’s “time to rotate the crops” and “bring new ideas and new energy to solving problems facing working people and our communities.”

His decision creates an open seat in Iowa Senate district 45, covering Iowa City and University Heights. One of the House districts contained in Bolkcom’s district will also be open, since State Representative Christina Bohannan is running for Congress rather than for re-election.

The other half of Bolkcom’s district is represented by Mary Mascher, a Democrat first elected to the Iowa House in 1994. Asked whether she plans to run for the Senate, seek re-election, or retire in 2022, Mascher told Bleeding Heartland on November 4, “I am still weighing my options.” UPDATE: Mascher announced on November 8 that she won’t run for the House again.

I expect crowded Democratic primaries next June for every open legislative district in the Iowa City area. The primary is the deciding election here, as Republicans have no chance and rarely even field candidates in this part of Johnson County. If Mascher runs for Senate, she would be the front-runner in a primary but probably would not clear the field. Bohannan’s victory over long-serving State Representative Vicki Lensing in the 2020 primary showed that many Democrats in the area are willing to support new legislators.
