George W. Bush's father was president before him, but the current White House incumbent has said, "I think if I had to have a mentor… it would have been Ronald Reagan." Now another father-son team has written a book about how well Bush lives up to the Reagan legacy. Reagan's Disciple: George W. Bush's Troubled Quest for a Presidential Legacy is a new book that compares Bush's presidency to that his mentor. Carl Cannon has covered the Bush White House for several publications. His co-author and father is Lou Cannon, who covered Ronald Reagan for the Washington Post.
