Missouri Senator Bob Dixon defeated incumbent Bob Cirtin by a 2-to-1 margin Tuesday in the Republican primary for Greene County Presiding Commissioner.
Dixon won with about 67 percent of the vote, according to the Greene County Clerk’s election results.
Dixon thanked Cirtin and his family for their service to Greene County.
"In a few hours, we will step into the bright, morning light of the fall campaign to elect Republicans," Dixon told a Republican watch party Tuesday at the University Plaza Hotel & Convention Center in Springfield.
He said the county faces challenges, including the budget, roads, bridges, domestic violence, and a drug crisis.
Dixon served in both the Missouri House and Senate before reaching term limits this year.
In November, Dixon will face Democrat Sara Lampe, who won about 84 percent of the Democratic votes, defeating her opponent, Donna Bergen.
