Nixon might have gone to China a time or two, but Arnold's practically taken up residence. His persona has left him essentially invincible on questions of toughness, and he's used the freedom for pretty progressive ends. It wasn't long ago that he signed into law a needle-exchange program that Gray Davis, afraid of being demagogued by the right, vetoed thrice. Now he's reforming California's shameful prisons by shunning the all-powerful prison guards union and forcing a move towards rehabilitation. Next up? Redistricting.
