San Joaquin County District 4 Supervisor Chuck Winn, the incumbent from Ripon who represents Escalon on the county board, is running for reelection and is being challenged by Julie Damron-Brown of Galt.

The June 5 primary election will also feature candidates for other county offices, with incumbent Sheriff-Coroner Steve Moore of Linden filing for reelection. He is facing a challenge from Pat Withrow of Escalon, who is a retired sergeant with the sheriff’s department.

Also seeking reelection, completing his first term in office, is 12th District State Assemblyman Heath Flora, who has filed the necessary paperwork with San Joaquin County to appear on the primary ballot.
