Other prominent Republican candidates running include Caitlyn Jenner, a former Olympic gold medalist who starred on the reality series "Keeping Up with the Kardashians"; former San Diego Mayor Kevin Faulconer; California Assemblyman Kevin Kiley; and John Cox, a businessman who was easily defeated by Newsom in the 2018 gubernatorial election.
Democrats had returned a larger share of those ballots than Republicans, meaning early results could show good signs for Newsom. But that might not last and the number of voters who turn out Tuesday will likely be crucial in deciding the race.
California historically takes weeks to count all the votes in statewide elections. In 2020, when nearly 18 million people cast ballots, a third of the votes in the presidential election were counted after election night. Two years earlier, more than 40% were counted after Election Day.
