Although the candidates represent districts, they run-county wide, and that can be expensive. Among the expenses: buying a refined list of likely voters, and hiring a campaign consultant who can develop an effective strategy.
With turnout expected to be low in the June election, candidates focus on the 100,000 or so people expected to vote in a county of 333,000 registered voters. Impressing those likely voters with key endorsements from elected officials is seen as crucial.
In the June election, if none of the eight candidates in the District 4 race gets more than 50 percent of the vote, the top two voter-getters run again in November, when the presidential race will attract a far larger voter turnout.
The District 4 seat is now occupied by Rose Jacobs Gibson, who is termed out. The district includes Menlo Park, Redwood City, East Palo Alto and unincorporated North Fair Oaks and Oak Knoll.
Running unopposed for re-election in their districts are incumbent supervisors Dave Pine and Adrienne Tissier.
Shelly Masur, a member of the Redwood City School Board, continues to lead in fundraising. She has raised $60,940, including $32,738 during the most recent reporting period, Jan. 1 to March 17.
Kirsten Keith, the mayor of Menlo Park, joined the race in early February and has raised $15,342. She also lent her campaign $10,000.
Guillermo "Memo" Morantes, a member of the county Board of Education, has raised $23,997, and has lent his campaign an additional $25,000.
Warren Slocum, the former San Mateo County chief elections officer and assessor-county clerk-recorder, joined the contest in early March and has raised $10,950.
Carlos Romero, a member of the East Palo Alto City Council, has raised $6,450 and lent his campaign an additional $35,000.
Ernesto "Ernie" Schmidt, a Redwood City planning commissioner, has raised a total of $12,299.
Andy Cohen, a member of the Menlo Park City Council, joined the race in early February and has raised $1,610, and lent his campaign an additional $8,000.
David E. Woods, a member of the East Palo Alto City Council, has raised a total of $1,000.
Three candidates spent money on political consultants: $23,300 spent by Mr. Morantes, $6,250 by Mr. Schmidt, and $4,000 by Ms. Masur.
