Only two candidates filed to be on the California primary ballot for Assembly, 59th district. One is the incumbent Republican, Phillip Chen. The other is Green Party member Victor Hernandez. It is therefore extremely likely that those two will both appear on the November ballot, although conceivably a write-in candidate in the primary might qualify.
The 59th district is in northern Orange County.
Hernandez is the only minor party member this year in California who is in a two-person primary race.
