SIOUX CITY, Iowa —
CNN projects Democrat Catelin Drey will win the State Senate special election.
The special election is for the Iowa Senate District 1 seat , which was left vacant after Rocky De Witt died of cancer in June.
Drey's victory against Republican Christopher Prosch flips a seat that breaks a Republican supermajority in the state.
Democrats can now block the governor's nominations that require two-thirds votes, including cabinet appointments, the Board of Medicine and Board of Regents.
