When the Washington Post asked readers to name the most underrated president, the winner was George H.W. Bush. As a reader put it: "The country owes 41 a collective apology for voting him out of office. Our deficit ballooned under Ronald Reagan, and Bush was left holding the bag. Conservative purists butchered him when he tried to get the country's finances under control. Bush also wisely understood what driving to Baghdad in 1991 would have meant — a long, bloody quagmire." Rounding out the top five: Lyndon Johnson, Jimmy Carter, Harry Truman and Calvin Coolidge.
