Next year, Arnold Schwarzenegger’s circus will leave Sacramento. The cigar tents will be packed up and his menagerie of lobbyists and hangers-on will follow him out of town. And like a departing circus it will leave in its wake a barren field strewn with garbage and elephant shit. Whoever is the next Republican nominee for governor will have to at least promise to clean up some of this mess. The last thing the state needs is a Margaret Thatcher wannabe.
