The runoff between Chad Whitefield and Tom Saltino is set for Aug. 8.
Whitefield garnered 1,366 votes in Tuesdays primary, while Saltino came in second with 1,115 votes but neither mustered the more than 50 percent of the vote needed to win outright. Ira Levy ran third with 861 votes.
The winner of the runoff will appear on the Nov. 7 general election ballot against Democrat Bill Whitener, who was unopposed for his partys nomination. Whitener netted 3,164 votes on Tuesday.
The Post 1 incumbent, Republican Tom Bennett, is not seeking a second four-year term.
Jeff Bishop nabbed the Democratic slot for the Post 4 race, beating Victoria Brooks 1,884 votes to 1,720 votes.
Im feeling very energized, Bishop said. Were ready to hit the ground running to take on the Republican in the fall, and I invite all of Victorias supporters to join me in the campaign. I think we stand for a lot of the same issues.
Bishop and Brooks ran neck and neck for most of the night, with a clear winner emerging only with the final precinct tallies.
Eddie Lumsden, who was unopposed for the Post 4 Republican nomination, garnered 2,654 votes.
Incumbent Chuck Hufstetler, a Republican, is stepping down to focus on his medical studies after spending eight years on the board.
Commission Chairman John Mayes, a Republican, has no challengers in his bid for re-election to the Post 5 seat this year. The other two commissioners, Garry Fricks and Jerry Jennings, began new four-year terms in 2005.
Election results were not available until after 12:30 a.m. on Wednesday, due to technical difficulties at the Floyd County Elections Office.
Voters may not cross over to the other partys primary in the runoff. Those who did not vote Tuesday may choose either partys ballot Aug. 8.
