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.

Democratic activists are highly motivated to take back the Iowa House majority, judging from the latest round of campaign finance reports for legislative candidates.

Iowa has never seen anything like this kind of fundraising for state House races.

Now that the deadline for candidates to qualify for the June primary ballot has passed, it’s time to revisit the 2020 Iowa House landscape. (A separate overview of state Senate races is in progress.)

Republicans now hold a 53-47 majority in the lower chamber, meaning Democrats need a net gain of four seats for control. Thanks to our state’s nonpartisan redistricting system, more than a dozen House districts should be highly competitive. This post covers 22 House districts that could fall into that category. One or both parties spent significant funds on twenty Iowa House races in 2018, not counting House districts 82 or 16, where Republican candidates ended up winning by small margins.

Since Bleeding Heartland first reviewed the House landscape last May, both parties have had some recruiting successes, while other districts still lack a top-tier challenger. The Secretary of State published the full list of Democratic and GOP primary candidates here. In some races that are currently uncontested, major parties may get candidates on the ballot later by holding a special nominating convention.
