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.

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.

UPDATE: Carlson announced on February 26 that he will not seek re-election. Original post follows.

Democrats have a solid recruit in one of the Iowa House seats on the second tier of the party’s target list for 2020. Muscatine City Council member Kelcey Brackett announced on December 13 that he will run for House district 91, now represented by three-term Republican Gary Carlson.

A rematch is brewing in one of the six Iowa Senate districts Republicans picked up in 2016. Longtime Muscatine firefighter Chris Brase announced on November 12 that he will run for Senate district 46, which he represented for four years before losing to current State Senator Mark Lofgren.

More than six dozen prominent Democrats endorsed former State Senator Rita Hart’s campaign for U.S. House on May 22. The list enclosed in full below includes activists from each of the 24 counties in Iowa’s second Congressional district. The best-known endorsers are former Iowa Lieutenant Governor and Secretary of Agriculture Patty Judge, former Iowa Democratic Party chair Sue Dvorsky, and twenty current or former state lawmakers.

Hart was already the clear favorite to win the nomination. She appears increasingly unlikely to face serious competition from the left in the Democratic primary. Iowa City business owner Veronica Tessler ruled out the race earlier this month. Former Bernie Sanders national delegate Daniel Clark, who ran in IA-02 as an independent last year, is now backing Hart. Johnson County progressives on the new list of Hart endorsers include State Senators Joe Bolkcom and Zach Wahls and State Representatives Mary Mascher and Amy Nielsen.

Scott County Supervisor Ken Croken is still considering a Congressional bid, he told Bleeding Heartland in a May 23 telephone interview. Croken said he and his team are collecting information about potential Republican candidates with a view to deciding who would be the best person to keep IA-02 in Democratic hands. He said the long list of Hart endorsers won’t affect his decision, which he will announce sometime after Memorial Day.

Hart’s news release mentioned eleven high-profile Scott County Democrats, including State Representatives Monica Kurth and Phyllis Thede, State Senator Jim Lykam, former Davenport Mayors Bill Gluba and Thom Hart, and former state lawmaker Frank Wood. Croken’s past contributions to some local Republican candidates would also be a problem in a primary race.

Speaking of Democrats in the Quad Cities area, Davenport attorney Ian Russell has ruled out running for Congress next year, he told Bleeding Heartland by phone on May 22. Russell said he talked to Hart about a week ago and “told her she’s going to be a very good candidate for the second district and that I’d support her.”

State Senator Nate Boulton and Fred Hubbell have locked up more support among state lawmakers than the five other Democrats running for governor combined.

Whether legislative endorsements will matter in the 2018 gubernatorial race is an open question. The overwhelming majority of state lawmakers backed Mike Blouin before the 2006 gubernatorial primary, which Chet Culver won. Last year, former Lieutenant Governor Patty Judge won the nomination for U.S. Senate, even though about 60 current and 30 former Democratic lawmakers had endorsed State Senator Rob Hogg.

Nevertheless, prominent supporters can provide a clue to activists or journalists about which primary contenders are well-positioned. Where things stand:
