The California governor's race remained undecided on Wednesday as postal ballot counting continued, with British-American former Fox News host Steve Hilton and former Biden cabinet secretary Xavier Becerra leading a crowded field in the state's jungle primary system. Hilton, a Republican endorsed by President Trump, was once a top adviser to former UK Prime Minister David Cameron and was known for helping shape Conservative Party strategy during the period that led to Brexit. He has campaigned on making California affordable by cutting taxes and regulations, solving the homelessness crisis and cooperating more closely with federal immigration enforcement. Becerra, a Democrat who served as health secretary under President Biden, has vowed to oppose Trump and promised to freeze insurance and utility rates. Billionaire climate activist Tom Steyer was in third place. The contest became the most expensive California gubernatorial race on record after a large field of Democrats splintered the vote, sparking fears among party leaders that two Republicans could advance in the deeply liberal state. The race was shaken when leading Democratic candidate Eric Swalwell dropped out and resigned from Congress in April amid sexual assault allegations. California's jungle primary picks the top two candidates regardless of party, and the volume of postal ballots meant a result could take several more days. Should Hilton advance to November's general election, he would face steep odds in a state where Democrats outnumber Republicans roughly two-to-one, and where the last Republican governor was Arnold Schwarzenegger.
