California: Software incompatibilities cited in review of missing Los Angeles County voter names | Los Angeles Times
Los Angeles County’s election software was unable to process a formatting change in state voter data, contributing to 118,500 names being omitted from eligible-voter rosters on election day in June, according to an executive summary of an independent review released Wednesday. There was no evidence of a security breach, the summary said. The county paid IBM Security Services $230,000 to investigate the foul-up, which officials said affected roughly 2.3% of registered voters across the county and 35% of voting locations. L.A. County elections chief Dean Logan said in June that the problem had no impact on voter eligibility and that poll workers were instructed on election day to give provisional ballots to people whose names did not appear on rosters. But the omissions prompted elected officials and civil rights groups to demand that the county review its election process.
