West Virginia Delegate Patsy Trecost is challenging Secretary of State Natalie Tennant in a Democratic primary.
The Harrison County lawmaker announced his bid for secretary of state Tuesday.
Trecost was elected to his first term as a delegate in 2014. He was previously the mayor and a city council member in Clarksburg.
Tennant was first elected in 2008 and won re-election in 2012. She is seeking a third term after losing a 2014 bid for U.S. Senate.
Morgantown Republican Mac Warner is also seeking the four-year office.
