Willie Brown thinks it's a good idea. And you can tell Newsom wants to consider it, since he knows there's nothing else obvious for him to do once his term as mayor is up -- and there are going to be a lot of options not too far down the road. Sen. Dianne Feinstein isn't getting any younger, and at some point she'll retire. If Jerry Brown doesn't get elected governor, the Democrats will be looking for someone very different in four years. But once a politician like Newsom is out of office and out of the spotlight, he'll have a hard time coming back.
So he could sit up there in the Lite Gov's office, doing what John Garamendi did -- taking on issues like cuts to the University of California (the Lt. Gov. sits on the Board of Regents) and making speeches about reform, and maybe he could get out in front of this constitutional convention stuff, and keep his name in the news, without having to make a single difficult or unpleasant decision that he can be blamed for later.
You know he wants to do it ....
But there's this problem, and for Newsom, it's very real.
