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.

A record number of women running for office in Iowa this year has translated into a record number of women who will appear on our state’s general election ballot. Iowa State University’s Carrie Chapman Catt Center for Women and Politics noted that 85 women (86 percent of female candidates on Iowa’s primary ballot) won their party’s nominations yesterday.

More women than ever will likely win Iowa House seats this November (current number: 28 out of 100). Female representation will almost certainly increase in the state Senate too and could exceed the previous record (ten out of 50 senators in 2013-2014). Follow me after the jump for details.

More Iowa women are running for office in 2018 than ever before, which could lead to record numbers of female state representatives and senators next year.

However, in other meaningful ways, Iowa’s legislature could become less diverse after the November election.

The Daily Kos Elections team has been compiling 2012 presidential election results by state legislative district as well as by Congressional district. Yesterday the Iowa numbers were added to the database. You can view Google documents with raw vote totals and percentages for Barack Obama and Mitt Romney by Iowa Congressional district here, by Iowa Senate district here, and by Iowa House district here.

Looking closely at the presidential vote in the legislative districts provides some insight about where the competitive Iowa statehouse races might be next year. After the jump I’ve highlighted some key data points related to the Iowa Senate races. Later I will post a separate diary with first thoughts about the Iowa House districts.
