Californians are pumping the brakes on Gov. Gavin Newsom’s plan to ban the sale of new gas-powered cars, with a new statewide poll showing the governor’s marquee climate policy has become a political headache. The survey by the nonpartisan Public Policy Institute of California found nearly two-thirds of Californians oppose Newsom’s 2035 gas-car mandate. Among likely voters, 65% said they oppose the plan, while just 34% support it. Opposition is even stronger among infrequent voters, signaling the governor faces broad resistance as he pushes one of his most aggressive climate initiatives.
