I see Gov. Jerry Brown took some backhanded swipes at our lieutenant governor in a visit to The Chronicle the other day. No surprise there. Even in his "do-nothing" job, Gavin Newsom is still a challenging figure for politicians throughout the state. He's articulate. He has movie-star looks. He has a great eye for issues, and he's young enough to be Jerry's son. That's also why Newsom strikes fear in other politicians. He has the potential for being a favorite of the Google generation. Brown has a special grudge against Newsom, of course, because Gavin tried to run against him...
