If Lt. Gov. Gavin Newsom is elected governor as expected, he’ll keep building the state’s two contentious public works projects: the bullet train and twin water tunnels. … The Democratic front-runner and his underdog rival, Republican businessman John Cox, competed in a debate Monday. But the train, tunnels and other vital state issues weren’t raised. So I [George Skelton] called Newsom and he phoned back. I also called and emailed Cox, but neither the candidate nor his staff responded.
