The Atlantic has an insightful interview called What Makes W. Tick? in which Sage Stossel questions historian and journalist Richard Brookhiser about the current American president and commander-in-chief. This appears to be a relatively fair and informed analysis of Bush's character, from his enlightened and successful managerial style to his past struggles with alcohol, some of his inspirations to reform and their subsequent impact on his concept of morality. From the article:
Abstract, imaginative thinking, Brookhiser emphasizes, is not the President's strong suit. And though Bush does take care to draw upon the counsel of intelligent, informed advisors, each with a different point of view, those varying viewpoints tend to fall only within a range of perspectives that reflect his pre-existing inclinations.
