Sterling Clifford, Brown's campaign spokesman, told me that Brown decided not to defend the measure because "The attorney general's job is to make sure that California stays within the confines of the U.S. Constitution."
And: "To say that state resources should be used defending a law that no one thinks is constitutional, I don't think holds up."
Problem: The California Supreme Court upheld Proposition 8 by a 6-1 vote -- which tells you there's a lot of room for debate. At least, Brown could have hired outside lawyers to represent the voters if he found defending Proposition 8 so discomforting.
As it is, I don't know why Brown is running for governor. He doesn't seem to relish his responsibilities as the state's top lawman. Methinks what Brown really wants to be is a federal judge.
