SANTA ANA, CA – March 22, 2024 – Registrar of Voters Bob Page today certified the official Orange County results of the March 5, 2024 Presidential Primary Election. 

Total voter turnout for the election was 37.7 percent. Of the 685,038 ballots cast by Orange County voters and counted, 84.5 percent cast a vote-by-mail ballot and 15.5 percent cast an in-person ballot at one of 183 Vote Centers throughout the county. 

Prior to certification, two audits were completed to verify the results of the election.  

The legally required One Percent Manual Tally examined and manually tallied 7,585 ballots from 26 precincts chosen at random. The hand count results were then compared with the election results that were produced by the County’s voting system.   

While not legally required, a risk-limiting ballot comparison audit was also conducted. During the audit, ballots among four contests selected by the Registrar of Voters were examined and compared to the original cast vote record. These 523 ballots were randomly selected using a state-approved audit software application to achieve a 95 percent confidence level that the election outcome was accurate. 

Both audits confirmed that the results of the election were correct. Details on the audits can be found at ocvote.gov/rla. 

A post-election logic and accuracy testing of Orange County's voting system equipment and software was also conducted. Test ballots were fed through all ballot scanning devices used in the election, and all the votes on the test ballots were accurately counted. 

The Orange County Registrar of Voters produces detailed reports and maps focusing on overall results and results by precinct, by districts, by cities, and more. These detailed reports can be found by visiting ocvote.gov/detailed-results and ocvote.gov/map-central.
