Zev Yaroslavsky, director of the Los Angeles Initiative at UCLA Luskin, spoke with CNBC about challenges facing Gavin Newsom, the next governor of California. Newsom inherits a booming economy and looks to steer the state in an increasingly progressive direction, with focuses on gun control, a single-payer healthcare system and affordable housing. His liberal-oriented ideologies put him in opposition to President Trump, who endorsed Newsom’s opponent, John Cox. Yaroslavsky, a former L.A. County supervisor, advised Newsom to focus on policy rather than constantly sparring with the president. “He’s going to have to take care of business in California and pick and choose his fights with Trump,”  Yaroslavsky said. “In my opinion, you can’t be, and shouldn’t be, a knee-jerk opponent of Trump on every single issue because people start to treat you as the usual suspect — and they don’t take you seriously anymore. I think he knows it.”
