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.

Some sobering facts about the bloodbath that was the 2016 election in Iowa:

Donald Trump carried eighteen state Senate districts that had voted for President Barack Obama in 2012.*

Eleven of those eighteen were even-numbered districts, which are on the Iowa ballot in presidential election years.

The four Republicans who already represented Obama/Trump districts all easily won another term in the Iowa Senate.**

But six of the seven Democratic senators up for re-election in Obama/Trump districts lost: Majority Leader Mike Gronstal (Senate district 8), Mary Jo Wilhelm (Senate district 26), Brian Schoenjahn (Senate district 32), Steve Sodders (Senate district 36), Tom Courtney (Senate district 44), and Chris Brase (Senate district 46).

With Republicans now enjoying a 32-18 majority in the upper chamber, Democrats need to win back at least a few Obama/Trump seats next year to have a realistic chance of regaining Iowa Senate control after the next round of redistricting.

Democrats have been actively campaigning in Senate districts 8 and 44 for some time. Now GOP State Senator Jeff Edler has a strong challenger in Senate district 36.
