Meh. He's obviously a sleazebag and he almost certainly won't be President, but as far as his job as Governor goes, he's been signing some important legislation trying to remedy some of California's worst problem (while sadly remaining hamstrung by the absurd fiscal constraints we inherited from MUH TAX REVOLT). Now if he could please just sign the farmworkers unionization bill...
California is running a $100 billion surplus (thank you Jerry Brown!) and Newsom's party has super-ultra-mega-supermajority control of both houses of the legislature. No, they can't unilaterally repeal prop 13 (which is good, because prop 13 is a very good thing actually) but there's a giant pot of money sitting waiting for him to tap.
Oh, and if he actually cared about improving California rather than running for President he'd have repealed CEQA a long time ago.
