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.

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.

Iowa’s new legislative maps create many more match-ups between Republican incumbents than Democrats. But two first-term Democratic senators, Claire Celsi and Sarah Trone Garriott, live in the new Iowa Senate district 16. Celsi announced in early November she’ll seek re-election in the district, which covers a blue-trending portion of Des Moines’ western suburbs.

Trone Garriott hasn’t decided how to proceed and told Bleeding Heartland in a recent telephone interview that she hasn’t ruled anything out. She has “lots of options,” she said, but “none of them are easy.”

Trone Garriott’s choice may depend in part on how Iowa Senate President Jake Chapman responds to being placed in a competitive district for the first time. Will the chamber’s second-ranking Republican stay in a district Joe Biden carried, or flee to safer nearby territory?

Less than two years after ending his campaign for governor and facing widespread calls to resign from the legislature, State Senator Nate Boulton drew no Democratic primary challenger or Republican general election opponent in Iowa Senate district 16.

However, Libertarian ToyA Johnson submitted nominating papers to run in this district shortly before the March 13 filing deadline.

Iowa Senate Minority Leader Janet Petersen has not assigned State Senator Nate Boulton to serve on any committees during the 2019 legislative session. In a written statement released on December 7, Petersen said, “I will defer making any committee assignments for Senator Boulton until the Senate Ethics Committee completes its ongoing investigation into the complaint filed against him.” In that complaint, filed last month, Sharon Wegner alleged sexual misconduct occurring in 2015, when Boulton was a candidate for the legislature.

Much of the legislature’s work happens in committees, so Petersen’s action will significantly limit Boulton’s ability to influence bills next year.

The move also indicates that Democratic leaders are unlikely to ask Boulton to lead the opposition to high-profile Republican bills during Senate floor debate, as happened several times in 2017 and 2018.

In contrast to 2012 and 2014, no recounts or special nominating conventions delayed the tabulation of results from Bleeding Heartland’s latest election contest.

Follow me after the jump to see which predictions in this comment thread most closely corresponded to unofficial results from the Iowa Secretary of State’s website.

Spoiler alert: yet again, I failed to win. One of these years…

Polls closed at 9 pm across Iowa. Any comments about today’s primary elections are welcome in this thread. Anecdotally, I heard reports of low turnout from various parts of the state all day long. I will be updating this post throughout the evening. For statewide results, check the Iowa Secretary of State’s results page. The Polk County Elections Office is posting results here.

Follow me after the jump for updates. The Des Moines Register posted the video of Patty Judge’s victory speech, because our local CBS affiliate cut away from it, and the NBC and ABC affiliates had ended their election coverage before then.

UPDATE: Boulton won this race by just under 53 percent of the vote to 47 percent.

One of the most closely-watched state legislative primary results tonight will be the race to represent the open Iowa Senate district 16, covering the east side of Des Moines and Pleasant Hill in Polk County. No Republican has filed to run in this overwhelmingly Democratic district. The two contenders seeking to replace retiring Senator Dick Dearden are his daughter, Pam Dearden Conner, and Nate Boulton. Bleeding Heartland posted background on both candidates here. Each has substantial support from influential local Democrats.

I love three things about this primary:

1) It is happening. Dearden announced his plans to retire six months before the filing deadline, giving all local residents plenty of time to enter the Senate race. He could have pretended to be seeking another term, then pulled his nominating papers on the last day, leaving time for only his daughter to file. Too many Iowa lawmakers, including three House Democrats this year, have engineered their retirements so that only favored insiders had a chance to consider running for office.

2) Both sides are working hard. Although some Iowa Democrats have a bizarre fear of competitive primaries, I see no downside to two candidates and a small army of volunteers knocking doors and making phone calls, trying to identify supporters and get them to vote. As of May 24, more than 1,200 voters in Senate district 16 had requested absentee ballots. Both campaigns were out in force this past weekend, enjoying perfect weather for canvassing. Boulton has raised and spent more money, as you can see from his and Conner’s latest disclosure reports, but both sides have done substantial district-wide voter outreach.

3) As far as I can tell, the candidates have stayed positive. Months ago, I was worried the Senate district 16 primary might turn nasty like the 2013 Des Moines City Council race between Chris Diebel and Skip Moore, which lit up social media and strained friendships.

May the best Democrat win. I’ve posted below some examples of campaign literature and direct mail supporting each candidate. You can find more information on the websites for Conner and Boulton.

It’s that time of year. For your chance at bragging rights in the Bleeding Heartland community, post a comment in this thread with your answers to the following fifteen questions sometime before 7 am central time on Tuesday, June 7.

Anyone can enter, whether you now live or have ever lived in Iowa. It’s fine to change your mind about some or all of your answers, as long as you post a comment with your new predictions before the deadline.

Only comments posted in this thread will be valid contest entries. Predictions submitted by e-mail or posted on Facebook or Twitter will not be considered. Please try to answer every question, even if it’s just a wild guess. We’re all guessing anyway, since no public polls have been published for most of these races.

Bleeding Heartland user ModerateIADem won this blog’s primary election prediction contests in 2010 and 2012. There was no clear winner two years ago.

Now that the deadline to compete in the Democratic or Republican primaries has passed, the field of candidates is set in most of the 100 Iowa House districts and 25 Iowa Senate districts that will be on the ballot this fall.

It’s time for a first look at chances to increase diversity in the state legislature for the next two years. The proportion of white lawmakers is unlikely to change, while the proportion of women could move in either direction.

When Nate Boulton announced his Iowa Senate campaign in September, he subtly indicated he would be a different kind of legislator than State Senator Dick Dearden, the longtime Democratic incumbent who is retiring this year. Boulton promised to “be an active and engaged representative of district interests” and to “bring bold progressive ideas and a fresh, energetic style of leadership to the Iowa Senate.”

Just a few months into his primary race against Pam Dearden Conner, the retiring senator’s daughter, Boulton sent a strong signal that he will be a more “active and engaged” candidate as well. Campaign finance disclosure forms show that Boulton raised $75,383 during the last four months of the year, a phenomenal total for a non-incumbent, first-time state legislative candidate in Iowa. Not only did Boulton out-raise his primary rival, he raised more than Dearden (a 22-year incumbent) has brought in cumulatively since 2008.

A generational battle is shaping up in the Democratic primary to replace State Senator Dick Dearden, who has represented parts of Des Moines in the legislature since 1995. Dearden recently disclosed plans to retire in 2016. Like last year’s campaign to replace Jack Hatch in Iowa Senate district 17 on the south side of Des Moines, the June primary will determine Dearden’s successor.

Senate district 16 covers heavily Democratic neighborhoods on the east side of Des Moines, and also the growing suburb of Pleasant Hill. A detailed map is after the jump. The latest figures from the Iowa Secretary of State’s Office indicate that the district contains 14,624 active registered Democrats, 6,978 Republicans, and 10,106 no-party voters. Dearden was unopposed in 2004 and defeated his Republican challengers by wide margins in 2008 and in 2012.

More candidates may enter the race later, but for now the primary will pit the incumbent’s daughter Pam Dearden Conner against labor attorney Nate Boulton. Iowa Labor Commissioner and former Secretary of State Michael Mauro endorsed Conner on Facebook this past weekend. She is his administrative assistant and also worked for him in the Polk County Election Office and the Secretary of State’s Office. Many other longtime friends and backers of Senator Dearden have expressed their support for Conner’s campaign on social media.

Nate Boulton is a partner in a law firm that has represented Iowa’s largest pubic employee union (AFSCME) in several high-profile cases against Governor Terry Branstad’s administration. Since last Friday, many Democratic activists in their 20s and 30s have promoted his candidacy on social media. Bouton’s on Twitter here, and his campaign is on Facebook here.

I enclose below press releases from each candidate, containing short biographies and statements of values. Both Conner and Boulton have strong pro-labor credentials and are pledging to support consensus Democratic priorities like education. Boulton’s statement hints at the case he will make in the primary, promising to “be an active and engaged representative of district interests” and to “bring bold progressive ideas and a fresh, energetic style of leadership to the Iowa Senate.” Such phrases allude to the fact that Dearden, while a solid vote in the legislature, has never been at the forefront of progressive fights. In fact, I’m hard-pressed to think of a cause he has led on, besides bringing back dove hunting, which isn’t a partisan issue. Dearden didn’t accomplish that longstanding goal until Governor Terry Branstad was back in office.

Two (or perhaps more) committed candidates working hard to identify and turn out supporters next June can only help Democratic GOTV in the general election. Here’s hoping for a competitive race that doesn’t turn bitter and negative, as happened in Senate district 17 last spring.

Democrats are assured of maintaining their majority in the Iowa Senate, with one race headed for a recount and another to be decided in a December 11 special election.
