Iowa Democrats were projected to score a major victory on Tuesday night, flipping control of the state's 1st Senate District in a special election — and breaking the Republican supermajority in that chamber.

The race was called by the Sioux City Journal and Siouxland Proud.

Catelin Drey, a mother and communications professional, faced off against GOP media consultant Christopher Prosch in the race. Unofficial results from Siouxland Proud show Drey winning by over 10 points, in a district that backed President Donald Trump by 11 points in 2024.

The seat was vacated due to the death of Republican state Sen. Rocky De Witt, who passed away after battling pancreatic cancer just into his first term of office.

Democrats were confident in flipping the seat, despite its heavy GOP lean at the presidential level, due to having held it until recently, as well as public anger among voters at the Trump administration, driving Democratic turnout.
