Kim Hanchette easily defeated Derek Kiszely in the Democratic primary.
The political newcomers were vying to replace Republican lawmaker Jim Fulghum, who is seeking a state Senate seat.
Hanchette, founder of Diabetes Management Solutions, has won the endorsement of all of the county’s Democratic House members. Kiszely has stressed his youth as an asset in the race, saying he would bring a needed perspective to the legislature.
Hanchette will face Gary Pendleton, a former Wake County commissioner.
