Contra Costa County Supervisor Susan Bonilla has endorsed Pleasant Hill Mayor Karen Mitchoff as her replacement.
After one term on the board, Bonilla is leaving the job this year and running in the Democratic primary for Assembly District 11.
“Susan believes that Karen’s experience with county government provides her with the necessary leadership on our county’s issues,” said Bonilla’s chief of staff Luis Quinonez.
As the incumbent, Bonilla’s endorsement will carry some weight among the county powerbrokers.
The only other officially declared candidate for supervisor is elected Central Sanitary District board member Mike McGill. Concord Councilwoman Laura Hoffmeister has said she wants to run but has not yet filed a candidacy declaration statement. Concord Councilwoman Helen Allen has said she will not run for the county seat.
The filing period for the June election is Feb. 16-March 12.
