In 2018, as part of Democrats' last hurrah in the rapidly right-trending state, incumbent Treasurer Michael Fitzgerald* won a tenth term in office. Fitzgerald's victory was driven by large margins in Iowa's few large cities, as well as a solid showing in rural counties, especially out east. Except for Attorney General Tom Miller (who faced no GOP opposition), Fitzgerald's win was the largest out of any Democrat statewide and remains the last time a Democrat won the state by >10%. Unfortunately for Fitzgerald, his tenth term would be his last, as he lost re-election in 2022 as part of a localized "red wave" in the state, solidifying Iowa as in the GOP camp.
*Fitzgerald was first elected in 1982, making him the longest serving State Treasurer in US history as of 2025.
