The San Mateo County Elections Office has certified the Feb. 5 election results and reported Tuesday that the turnout was 59.3 percent, far exceeding the 48.6 percent turnout in the 2004 presidential primary.
Of the 357,075 registered voters in the county, a total of 211,697 cast ballots, said Chief Elections Officer Warren Slocum.
While the highest in several years, the turnout was not a record and fell short of Mr. Slocum's pre-election estimate that the turnout "may reach as high as 71 percent."
The presidential primary turnout has not exceeded 60 percent since 1980, he said in a press release.
Of those who voted, 45.3 percent cast their ballots by mail.
Before certifying the vote, the Elections Office conducted a manual hand count of 1 percent of the precincts, selected at random. All votes, whether cast on eSlate machines or by paper ballots, are tallied by machines after the polls close, said Mr. Slocum.
"We were pleased -- and not surprised -- to find that the manual tally results compared to the machine tally results matched exactly," Mr. Slocum said.
The "Statement of the Vote," set to be approved by the San Mateo County Board of Supervisors on March 11 is a 150-page document that parses the count by such factors as precinct, city and political district.
