The Democratic National Committee is putting more volunteers in Iowa ahead of Tuesday’s special election for the state Senate, in which Democrat Catelin Drey is seeking to flip a GOP seat and break apart the chamber’s Republican supermajority.

Drey will face Republican Christopher Prosch in the election for Iowa Senate District 1 to succeed the late GOP Sen. Rocky De Witt, who died in June from pancreatic cancer. Witt held the seat from 2022 until his death.
