UPDATE: Republicans selected Adrian Dickey and Democrats selected Mary Stewart at special nominating conventions on January 7. Original post follows.

Voters in a battleground southeast Iowa Senate district will soon choose a successor to Republican State Senator Mariannette Miller-Meeks.

U.S. House Speaker Nancy Pelosi confirmed on December 30 that the House will seat Miller-Meeks, who was certified the winner by six votes in Iowa’s second Congressional district. The same day, Miller-Meeks confirmed that she is resigning from the Iowa legislature, effective January 2.

To my knowledge, no candidate has announced plans to run in Senate district 41 early next year. During a December 30 telephone interview, Democrat Mary Stewart said she was considering the race but had no timetable for deciding. Miller-Meeks defeated Stewart in 2018 by 11,460 votes to 10,652 (51.7 percent to 48.1 percent).

Former Republican State Senator Mark Chelgren represented the district for eight years, retiring in 2018. He hadn’t heard about Miller-Meeks’ resignation before speaking to Bleeding Heartland by phone on December 30. Chelgren said he would consider running for the Senate again but wasn’t ready to give a formal statement, since he hadn’t discussed the matter with his family or Republican colleagues.

Though recent voting patterns in the area favor Republicans, turnout for a mid-winter special election is a question mark.

Politics watchers from around the country are watching Iowa’s U.S. Senate race today, but arguably the battle for the Iowa House is more important for our state’s future. Democrats need a net gain of four seats for a majority or three seats for a 50-50 chamber that would block the worst excesses of the Republican trifecta.

The 2020 playing field is even larger than usual, in part because Democrats finally have the resources to compete with Republicans in the battleground House districts.

I enclose below a brief final look at each House district, with the latest voter registration figures (as of November 2), absentee ballot totals (as of November 3), campaign spending by both parties, and recent voting history. This post from early October has more background on each campaign, which influenced my ratings.

Democrats have good prospects to win control of the chamber, with many potential targets. If Republicans cling to a majority, it will probably be with only 51 seats.

I’ve always enjoyed writing about legislative happenings and campaigns, since my first year on the job as an analyst covering Russian domestic politics during a parliamentary election year.

While most political reporters were understandably assigned to follow the many presidential candidates visiting Iowa in 2019, I made it a priority to keep an eye on down-ballot races. The 2020 Iowa House and Senate elections may affect our daily lives more than whether Donald Trump or the Democratic nominee wins our state’s electoral votes. For one thing, breaking the GOP trifecta is the only way to guarantee that Iowa preserves nonpartisan redistricting for the coming decade.

I’m proud that Bleeding Heartland provided more in-depth coverage of potentially competitive state legislative races than any other Iowa news source this year. All of those stories are linked below.

State Representative Mary Gaskill will seek a tenth term in 2020, House Democrats announced on November 7.

That’s good news for Democrats, who might have had a difficult seat to defend if Gaskill had chosen to retire.

Republicans used their control over state government to inflict tremendous damage on Iowa during the 2019 legislative session: underfunding education, blocking steps that would improve Medicaid services, dismantling effective sex education programs, further undermining workers’ rights, targeting health care for transgender Iowans, and giving Governor Kim Reynolds the ability to pack our highest courts with conservative ideologues.

The disastrous outcomes underscored the urgent need for Democrats to break the Republican trifecta in 2020. The Iowa House is the only realistic path for doing so, since Reynolds won’t be up for re-election next year, and the 32-18 GOP majority in the Iowa Senate will take several cycles to undo. State Representative Andy McKean’s recent party switch improved Democratic prospects, shrinking the Republican majority in the chamber from 54-46 to 53-47. Nevertheless, a net gain of four House seats will be no easy task for Democrats.

The Daily Kos Elections team calculated the 2018 election results for governor and state auditor in every Iowa House district. Jeff Singer discussed their key findings in a May 2 post: Reynolds carried 60 state House districts, Democratic nominee Fred Hubbell just 39. The “median seat backed Reynolds 51.0-46.3, a margin of 4.7 points. That’s about 2 points to the right of her statewide margin of 2.8 points.” Eight Democrats represent districts Reynolds carried, and one (Dave Williams) represents a district where Reynolds and Hubbell tied, while “only one Republican is in a Hubbell district.”

I’d encourage all Iowa politics watchers to bookmark the DK Elections number-crunching, as well as the team’s spreadsheet on 2016 presidential results by House district.

The Daily Kos team also looked at the 2018 voting for state auditor, seeking clues on which House seats might be within reach for Democrats. I don’t find that angle as useful. Previous State Auditor Mary Mosiman ran a terrible campaign. Not only did Rob Sand outwork Mosiman on the trail, he ran unanswered television commercials for six weeks, allowing him to go into election day with higher name ID than the incumbent, which is almost unheard of. Sad to say, Democrats won’t be outspending incompetent, little-known GOP candidates in the 2020 state legislative races.

Here’s my first take on both parties’ best pickup opportunities. What appear to be competitive state House seats may shift over the coming year, depending on candidate recruitment and incumbent retirements, so Bleeding Heartland will periodically return to this topic.
