This post has been updated with unofficial results from the November 5 election, as well as the final pre-election campaign finance disclosures and absentee ballot totals as of November 2. Original post follows.

Republicans currently hold 34 Iowa Senate seats—the largest GOP contingent in that chamber since 1973. Democrats are not realistically contending to regain the Senate majority in November. So why pay any attention to these legislative races?

Although the most competitive state Senate races won’t determine control of the chamber, they could reveal a lot about each party’s strengths with certain kinds of voters. A good night for Republicans would indicate that the Trump-era realignment has moved further into Iowa’s former blue regions. A good night for Democrats could pull the GOP below the two-thirds threshold, which has allowed Senate Republicans to confirm all of Governor Kim Reynolds’ nominees without any support from the minority party.

This post highlights four state Senate districts at most risk of flipping, and another seven districts where even without a big investment by Democrats or Republicans, the results could shed light on broader political trends in Iowa. A forthcoming article will cover state House races to watch in 2024.

The Iowa Senate convened in Des Moines on January 8 for the first day of the 2024 legislative session. Although the balance of power remains the same (34 Republicans, sixteen Democrats), I’m publishing a new version of this post to note changes in leadership or among the chairs, vice chairs, and members of standing Senate committees.

Fourteen senators (nine Republicans, five Democrats) were elected to the chamber for the first time in 2022. Seven of them (four Republicans and three Democrats) previously served in the Iowa House.

Fifteen senators are women (eight Democrats and seven Republicans), up from twelve women in the chamber prior to the 2022 election and more than double the six women senators who served prior to the 2018 election.

Democrat Izaah Knox is the second Black state senator in Iowa history. The first was Tom Mann, a Democrat elected to two terms during the 1980s. The other 49 senators are white. No Latino has ever served in the chamber, and Iowa’s only Asian-American senator was Swati Dandekar, who resigned in 2011.

Democrat Janice Weiner became the first Jewish person to serve in the Iowa Senate since Ralph Rosenberg left the legislature after 1994. Democrat Liz Bennett became the first out LGBTQ state senator since Matt McCoy retired in 2018.

The Iowa Senate began its 2023 session on January 9 with 34 Republicans and sixteen Democrats, the largest majority seen in the chamber for about five decades. Five of the last seven Iowa general elections have been Republican waves.

Fourteen senators (nine Republicans, five Democrats) were just elected to the chamber for the first time in November. Seven of them (four Republicans and three Democrats) previously served in the Iowa House.

I enclose below details on the majority and minority leadership teams, along with all chairs, vice chairs, and members of standing Iowa Senate committees. Where relevant, I’ve mentioned changes since last year’s legislative session. The Senate has added a new Technology Committee and renamed what used to be “Labor and Business Relations” as the Workforce Committee.

Some non-political trivia: the 50 Iowa senators include two Taylors, a Democrat and a Republican. As for first names, there are three Jeffs and two men each named Mark, Mike, and Dan.

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.

The Iowa Senate convened for its 2022 session on January 10 with 32 Republicans and eighteen Democrats. Twelve senators are women (seven Democrats and five Republicans), up from eleven women in the chamber prior to the 2020 election and double the six women senators who served prior to the 2018 election.

I enclose below details on the majority and minority leadership teams, along with all chairs, vice chairs, and members of standing Iowa Senate committees. Where relevant, I’ve mentioned changes since last year’s legislative session. The biggest change: Republican Dave Rowley was elected in December to succeed Republican Zach Whiting, who resigned to take a job in Texas.

All current state senators are white. The only African American ever to serve in the Iowa Senate was Tom Mann, elected to two terms during the 1980s. No Latino has ever served in the chamber, and Iowa’s only Asian-American senator was Swati Dandekar, who resigned in 2011.

Some non-political trivia: the 50 Iowa senators include two Smiths, a Democrat and a Republican, and two Taylors, a Democrat and a Republican. As for first names, there are three Jeffs and two men each named Zach, Craig, Mark, Dan, Jim, and Tim.

Now that Iowa’s political maps for the next decade have been finalized, it’s time to look more closely at the district lines in and near larger metro areas. Although most districts anchored in cities are safe for Democrats, these metros will include quite a few battleground Iowa House and Senate races over the next two election cycles. Several “micropolitan” districts containing mid-sized cities remain competitive as well, and a forthcoming post will cover those maps.

I’ll write more about the political landscape of individual House or Senate districts once lawmakers and other contenders have confirmed their plans for next year. Several incumbent match-ups have already been worked out, and I’m continuing to update this post. (Please send tips on candidate announcements.)

I’ve grouped each Iowa Senate district with the two state House districts it wholly contains.

Iowa lawmakers overwhelmingly approved the Legislative Services Agency’s second redistricting plan on October 28, by 48 votes to 1 in the Iowa Senate and 93 votes to 2 in the House. Democrats had already committed to approving any nonpartisan maps. Republicans liked that this plan (unlike the first LSA proposal) creates four U.S. House districts that Donald Trump carried. It also gives the party an excellent chance to maintain their Iowa House and Senate majorities.

Republican State Senator Ken Rozenboom cast the only vote against the maps in the upper chamber. The plan puts him in the same district as his GOP colleague Adrian Dickey.

In the lower chamber, only GOP State Representatives Tom Jeneary and Jon Jacobsen voted against the redistricting plan. Both are placed in House districts with other Republican incumbents, but Jacobsen told Bleeding Heartland in a telephone interview that’s not why he opposed the plan. Rather, he said the legislative maps carve up Pottawattamie County outside Council Bluffs into several districts represented by incumbents who live elsewhere.

I’ll have more to say about some legislative districts in forthcoming posts. For now, here are the basics about the plan Governor Kim Reynolds will soon sign into law. UPDATE: The governor signed the bill on November 4.

The Iowa Senate convened for its 2021 session on January 11 with 31 Republicans, eighteen Democrats, and one vacancy in the district formerly represented by Mariannette Miller-Meeks. A record twelve senators are women (seven Democrats and five Republicans), up from eleven women in the chamber last year and double the six who served prior to 2018.

I enclose below details on the majority and minority leadership teams, along with all chairs, vice chairs, and members of standing Iowa Senate committees. Where relevant, I’ve mentioned changes since last year’s legislative session. A few committees have new Republican leaders.

All current state senators are white. The only African American ever to serve in the Iowa Senate was Tom Mann, elected to two terms during the 1980s. No Latino has ever served in the chamber, and Iowa’s only Asian-American senator was Swati Dandekar, who resigned in 2011.

UPDATE: Republican Adrian Dickey won the January 26 special election to represent Senate district 41, giving the GOP a 32-18 majority. After he’s sworn in, I’ll note his committee assignments below.

Second in a series interpreting the results of Iowa’s 2020 state and federal elections.

The non-profit 50-50 in 2020 dissolved early this year after working for a decade to increase women’s representation in Iowa politics. Although our state has elected a woman governor, a woman to the U.S. Senate (twice), and will have women representing three of the the four Congressional districts for the next two years, we have a long way to go toward parity in the Iowa legislature.

When lawmakers convene in Des Moines in January, women will make up one-quarter of the Iowa Senate for the first time. However, the number of women serving in the House will drop below one-third of the chamber.

Iowans will elect 25 state senators today. Those races have attracted far less attention than this year’s Iowa House races, because Republicans have a lopsided 32-18 majority in the upper chamber and only a 53-47 advantage in the House.

Nevertheless, it’s important to keep an eye on the Senate races, because this year’s outcome will influence Democratic prospects under the new map coming in 2021.

This overview covers five districts where both parties are spending six-figure amounts, seven districts where Republicans spent a significant amount, and four more districts where the results could shed light on political trends in various parts of the state, even though neither Democrats nor Republicans targeted the race.
