An error with an electronic voting system gave President Bush 3,893 extra votes in suburban Columbus, elections officials said. Franklin County's unofficial results had Bush receiving 4,258 votes to Democrat John Kerry's 260 votes in a precinct in Gahanna. Records show only 638 voters cast ballots in that precinct. In one North Carolina county, more than 4,500 votes were lost because officials mistakenly believed a computer that stored ballots electronically could hold more data than it did. And in San Francisco, a malfunction with custom voting software could delay efforts to declare the winners of four races for county supervisor. In the Ohio precinct in question, the votes are recorded onto a cartridge. On one of the three machines at that precinct, a malfunction occurred in the recording process, Damschroder said. He could not explain how the malfunction occurred. Damschroder said people who had seen poll results on the election board's Web site called to point out the discrepancy. The reader also recorded zero votes in a county commissioner race on the machine.
