All information below about the 2020 primary election is based on information from the Orange County Registrar of Voters.
There are 1703 precincts in the County of Orange. About a third have been counted so far.
Democratic presidential primary
For candidates currently above the 15% threshold required to be awarded delegates:
| Candidate | # Votes | % Votes |

| JOSEPH R. BIDEN | 54,478 | 24.53% |
| MICHAEL R. BLOOMBERG | 34,595 | 15.58% |
Elizabeth Warren and Pete Buttigieg have not reached the 15% threshold.
President Trump currently enjoys almost 94% of the votes cast by Republicans.
State Senate and Assembly
Because so many of the districts cross county lines, I have elected to gather these in a separate article on statewide primary election results.
