Madera County Supervisor David Rogers won his re-election bid Tuesday night, while Supervisor Tom Wheeler remained in a tight race.
District 1 Supervisor Brett Frazier ran unopposed.
With all of the precincts reporting by early Wednesday morning, voters in District 2 were poised to return Rogers to another four-year term with nearly 66 percent of the vote.
His challenger, Al Galvez, president of the Madera Unified School District board, had about 33 percent of the vote. Rogers said he was humbled that voters in his district re-elected him to his second four-year term.
"I let the voters decide and they felt I was doing the job they wanted," Rogers said. "And I am happy to have their support."
Rogers said one of the biggest issues facing Madera County is the need for more water. He plans to work on enlarging Madera Canal, expanding the area's reservoirs and finding ways to boost the supply of groundwater.
In the tightest race of the night, incumbent Wheeler faced a battle for his District 5 seat.
Wheeler edged ahead of challenger Marc Sobel, who retired from the radio business in Southern California and now owns several rental properties in Oakhurst.
Wheeler had 50.64 percent of the vote to Sobel's 45.69 percent, a difference of 358 votes.
Another challenger in the District 5 race, Nokomis Hernandez, received less than 4 percent of the vote.
Madera was a Voter's Choice Act county, meaning all voting was by mail or in person at central locations. The Madera County clerk's office still must process and count any vote-by-mail or provisional ballots turned in at polling places on Tuesday, as well as mailed ballots postmarked on or before Tuesday that are received by Friday.
