Sandie Arnott, the current deputy treasurer for San Mateo County, got the most votes in the June 8 primary election for county treasurer, but she will face a run-off election in November because she did not receive the necessary majority of 50 percent plus 1, said David Tom, spokesman for the county's elections office.
Ms. Arnott's opponent in November will be San Mateo County Community College District board member Dave Mandelkern, who came in second in a four-way race.
The treasurer acts as a banker for public agencies in the county such as school and sewer districts. The treasurer also manages these agencies' investment portfolio, currently valued at about $2.6 billion. Lee Buffington, who has been the treasurer for 25 years, retires at the end of the year.
In the race, Ms. Arnott got 38 percent of the nearly 61,000 votes cast in county's 456 precincts, according to semi-official results from the registrar's office.
Mr. Mandelkern took second place with 17,000 votes, or 28 percent, the report said.
Bringing up the rear were certified public accountant Joe Galligan with 25 percent and investment adviser Richard Guilbault with 9 percent.
