Planning Commissioner Colin McCarthy, who serves as president of the conservative Costa Mesa Taxpayers Assn., announced Monday that he is running for City Council in November.
McCarthy, an attorney, is a supporter of the City Council majority, which is seeking to outsource some city employees and replace them with outside contractors.
With Mayor Eric Bever termed out, there will be three open seats on the council.
Also in the race are Councilmen Gary Monahan and Steve Mensinger, as well as medical marijuana advocate Sue Lester.
Attorney John Stephens, a political ally of Newport-Mesa Unified school board Trustee Katrina Foley, is also considering a run. Stephens' views so far are in opposition to the council majority's.
