Iowa Democratic state senator-elect Catelin Drey

In what could be a harbinger of future Democratic success, a Democrat has just won the special election for a state senate seat in Iowa that Republicans have held for more than a decade.

The Hill reported that Democrat Catelin Drey is projected to win Tuesday's special election for Iowa's District 1 state senate race, defeating Republican Christopher Prosch by nearly 10 percentage points. The special election will fill the seat vacated by the late Republican state senator Rocky De Witt, who died from cancer in June. Drey will then have to run for reelection next year for a full four-year term.

With Drey's victory, Republicans no longer have a supermajority in the Iowa legislature. While the GOP still controls the House of Representatives, the Iowa governor's mansion and has a majority in the state senate, Drey's win means that Republicans no longer have the two-thirds majority necessary in the senate to confirm Republican Gov. Kim Reynolds' nominees on a party-line vote.

"Iowa Democrat Catelin Drey is on track to win her Special Election for the Iowa State Senate tonight in a stunning over performance, BREAKING the GOP's super majority in the Iowa State Senate," Iowa Democratic state senator Zach Walls wrote on X, including a screenshot of vote totals. "This is huge."

According to Ballotpedia, Iowa's 1st state senate district has been solidly in Republican hands since 2010. De Witt won his election in 2022 by double digits. His predecessor, Dave Rowley, won in 2018 with more than 75 percent of the vote. And in 2018, Republican Zach Whiting won the seat with 98.2 percent of the vote. Drey is the first Democrat to represent the 1st state senate district (which includes most of Sioux City and points east) since 2006.

The Hill reported that Drey's victory follows a string of other Democratic successes in down-ballot races since the start of President Donald Trump's second term. In January, Democrat Mike Zimmer won a special election for Iowa's 35th state senate district, where Trump won in 2024 by roughly 20 percentage points.

Democratic Legislative Campaign Committee president Heather Williams told the Hill that the party's recent victory in Iowa signals that Americans are opposed to the "failing MAGA agenda." She further added that Drey's win on Tuesday night should be seen as a "flashing warning" to Republicans.
