Normally, big changes in the Iowa legislature happen the year after a general election. But there has been much more turnover than usual in the Iowa House since last spring. With two Republicans running for Congress and another resigning from the legislature to take a Trump administration job, a chain reaction leaves ten House committees with a different leader for the 2026 session.

The overall balance of power remains the same: 67 Republicans and 33 Democrats in the chamber. Each party has some new faces in the leadership team, however. All of those details are listed below, along with committee assignments and background on all committee chairs and ranking members. As needed, I’ve noted changes since last year’s session.

Nineteen House members (fourteen Republicans and five Democrats) are serving their first term in the legislature—three more than in 2025, due to special elections that happened last March, April, and December.

The number of women serving in the chamber crept up from 27 at the beginning of 2025 to 29 as of January 2026, since Democrat Angel Ramirez succeeded Sami Scheetz in House district 78 and Republican Wendy Larson was elected to replace Mike Sexton in House district 7. The ratio of 71 men and 29 women is the same as during the 2024 session.

Six African Americans (Democrats Jerome Amos, Jr., Ruth Ann Gaines, Rob Johnson, Mary Madison, and Ross Wilburn, and Republican Eddie Andrews) serve in the legislature’s lower chamber. Gaines chairs the Iowa Legislative Black Caucus.

Republican Mark Cisneros became the first Latino elected to the Iowa legislature in 2020, and Democrat Adam Zabner became the second Latino to serve in the chamber in 2023, and Ramirez the chamber’s first Latina member in 2025.

Republican Henry Stone became the second Asian American ever to serve in the House after the 2020 election. Democrat Megan Srinivas was first elected in 2022. The other representatives are white.

Three House members identify as part of the LGBTQ community: Democrats Elinor Levin and Aime Wichtendahl, and Republican Austin Harris. As for religious diversity, Levin and Zabner are Jewish. Srinivas is Hindu. The chamber has had no Muslim members since Ako Abdul-Samad retired in 2024.

Some non-political trivia: the 100 Iowa House members include two with the surname Meyer (a Democrat and a Republican), two Johnsons (a Democrat and a Republican), and a Thompson and a Thomson (both Republicans).

As for popular first names, there are four men named David (one goes by Dave), three named Thomas or Tom, three Roberts (two Bobs and a Bobby), a Jon and a John, a Josh and a Joshua, a Mike and a Michael, and two men each named Jeff, Dan, Brian, Steven, Chad, Austin, and Mark. There are also two Elizabeths (one goes by Beth) and two women each named Jennifer, Heather, Megan, and Shannon. As recently as 2020, four women named Mary served in the Iowa House, but now there is only one.

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.

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.

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, three Zachs, and two men each named Craig, Mark, Dan, Jim, and Tim.

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.

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.
