There have been positive signs. Passionate and thoughtful conservatives have participated in forums and salons on fixing the state and have offered terms of engagement. You won't hear Proposition 13's most ardent defenders agree that it is on the table or, for now, entertain even the idea of a "split roll" in which taxes on commercial property rise with the market. But how about fixing the rules that allow businesses to use stock swaps to hide property transfers without triggering reassessment? Some Proposition 13 supporters have gotten on board with that idea, just as some liberals and government-reform groups are willing to countenance the supermajority required to approve tax hikes.
