Republican Warren Davidson will take John Boehner's seat in Ohio's 8th District Congressional race.
Davidson will complete Boehner's term and be in a strong position to win the general election for a full term in the next Congress.
He defeated Democrat Corey Foister and Jim Condit Jr. who was nominated under the Green Party banner.
The Republican, who won his party's nomination by topping a 15-candidate primary field, won Tuesday's contest with 77 percent of the vote.
On Monday, Ohio Secretary of State Jon Husted's office said nearly 3,600 ballots had been cast early in the race. He appeared Tuesday morning on FOX19 NOW Morning News to discuss it.
The unofficial results show that 28,110 ballots cast with 5.96 percent of voter turnout.
Open seats have been rare in Ohio, which has very incumbent-friendly House districts.
Polls closed 7:30 p.m.
