You won’t be seeing much of California’s gubernatorial candidates this fall — at least, you won’t be seeing much of them together. The only debate between Democrat Gavin Newsom and Republican John Cox took place on KQED’s Forum radio program Monday. Prompted by host Scott Shafer, the two had a lengthy exchange about the state’s approach to climate change. Newsom applauded the state’s aggressive goals to reduce greenhouse gas emissions, while Cox said they would impose too high a price for the average Californian.
