National Democrats are celebrating the results of a special election for the Iowa State Senate, after Democrat Catelin Drey won in a district President Donald Trump carried by 11 points in 2024 to break a Republican supermajority of the chamber.

Republicans argue the low turnout race won’t reflect the voters who come out to support the party in the midterms, and that the results are influenced by the Democratic National Committee’s efforts to inject national money and volunteers into the race.

But the results are a potential warning sign for Republicans and suggest Democratic voters may be more engaged heading into next year’s elections, where control of Congress is at stake.

Drey won with 55% of the vote, with Republican Christopher Prosch garnering 44%, according to preliminary results from the Woodbury County Auditor’s Office.

“For the fourth special election in a row, Iowa voted for change,” Iowa Democratic Party Chair Rita Hart said after Drey’s victory.

“Our state is ready for a new direction and Iowa Democrats will keep putting forward candidates who can deliver better representation for Iowans,” Hart added.

Ken Martin, chair of the Democratic National Committee, said on Wednesday the party mobilized more than 30,000 volunteers to aid Drey and Iowa Democrats.

Martin, in a statement touting Drey’s victory, said Iowans are “putting Republicans on notice and making it crystal clear: any Republican pushing Trump’s unpopular, extreme agenda has no place governing on behalf of Iowa families.”

“That’s why all year long, Iowans have been electing Democrats ready to fight for working Iowans. Make no mistake: when Democrats organize everywhere, we win everywhere, and today is no exception,” Martin said.

This is the second time this year that Democrats have won a special election in Iowa. In January, they flipped another Iowa State Senate seat in a GOP area that President Trump won by 21 points last November.

The result of Tuesday’s special election also has practical implications for the state. Without a supermajority, Republicans can no longer confirm the governor’s appointees without Democratic support.

Iowa Republican Party chair Jeff Kaufman, on social media, downplayed the win for Democrats.

“National Democrats were so desperate for a win that they activated 30,000 volunteers and a flood of national money to win a state senate special election by a few hundred votes,” Kaufman wrote on X. “If @DNC thinks things are suddenly so great again for them in Iowa, they will bring back the caucuses.”
