Linda Greenhouse on the politics of fear, and what happens when people stop being afraid. When he ran for president the second time almost half a century ago, Richard M. Nixon made Earl Warren’s Supreme Court a target of his campaign. It was a brilliant move.... Fear was in the air, fear that Nixon and his henchmen knew how to exploit. I thought of Nixon last week as I watched the parade of Republican would-be presidents outdoing one another in denouncing the "lawless" and "brazen" Supreme Court.
