Editor’s note: This analysis has been updated with unofficial results from all the races. Original post follows.

The major parties have spent hundreds of thousands of dollars on the most competitive 2022 Iowa House and Senate races.

This post highlights seven state Senate districts where one or both parties have spent large sums, and another seven where even without a big investment by Democrats or Republicans, the results could shed light on political trends.

All voter registration totals listed below come from the Iowa Secretary of State’s office, as reported on November 1. All absentee ballot figures come from the Secretary of State’s office, as reported on November 7. All past election results come from the map Josh Hughes created in Dave’s Redistricting App.

All figures for in-kind spending by the Iowa Democratic Party or Republican Party of Iowa come from filings with the Iowa Ethics and Campaign Disclosure Board. I focus on in-kind spending, because candidates in battleground Iowa legislative races typically give most of their funds to the state party. The party then covers the bulk of the large expenditures for direct mail and/or television, radio, and digital advertising.

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.
