Take George W. Bush: He was an unpopular two-term president. Three times, his approval rating dropped to 25 percent. [To be fair, he also had the highest approval rating of all time, very briefly. But that was immediately after 9/11 -- and in the wake of domestic terrorism, a well-dressed mannequin's approval rating might have hovered around 50.] During his last two years in office, he was hammered nonstop, periodically classified as the worst U.S. president since Ulysses Grant or James Buchanan. Yet was Bush a villain? No. He was not. He was never, ever calculating. He didn't know the most (which is not to say he was dumb), and he didn't care the least (which is not to say he was a paragon of empathy). He was just the guy who ended up with the job. The villain of his administration ended up being Vice President Dick Cheney, a frosty puppet master who radically expanded the powers of the presidency even though he was not the president.
