assessing Ronald Reagan. There are so many basic questions that even his friends cannot quite figure out, such as (to start with the most basic one): Was he smart? From the brilliant-versus-clueless question flows even more complex ones. Was he a visionary who clung to a few verities, or an amiable dunce who floated obliviously above facts and nuances? Was he a stubborn ideological coot or a clever negotiator able to change course when dealing with Congress and the Soviets and movie moguls? Was he a historic figure who stemmed the tide of government expansion and stared down Moscow, or an out-of-touch actor who bloated the deficit and deserves less credit than Gorbachev for ending the cold war? The most solidly reported biography of Reagan so far--indeed, the only solidly reported biography--is by the scrupulously fair newspaperman Lou Cannon, who has covered him since the 1960s. Edmund Morris, who with great literary flair captured the life of Theodore Roosevelt, was given the access to write an authorized biography, but he became flummoxed by the topic; he took an erratic swing by producing Dutch, a semifictionalized ruminative bio-memoir, thus fouling off his precious opportunity. Both Garry Wills in his elegant 1987 sociobiography, Reagan's America, and Dinesh D'Souza in his 1997 delicate drypoint, Ronald Reagan, do a good job of analyzing why he was able to make such a successful connection with the American people.
