175 Ballot Machine Computer Chips Go Missing

San Diego County election officials say about 175 computer chips meant to power machines that will tally ballots in February's presidential primary disappeared after they were shipped from state offices in Sacramento.

Registrar Deborah Seiler says the cardboard tubes that were supposed to contain the chips arrived empty on Monday. The chips only work in the optical scanners used to count paper ballots. The manufacturer says the chips can be quickly replaced.
