Californians seem to have remarkably good attitudes about the sacrifices they'll make as the drought heads into its fourth year. Based on polls, they even are supportive of crackdowns on excessive water use, which may explain Gov.

But how tolerant will the public remain about slashing water use once they realize how state and federal officials are using the state's dwindling resources?
