>Mr. Bush praised Mr. Clinton for befriending his father, the elder President George Bush, after defeating him in the 1992 presidential election. “They ended up having a friendship, so you have to ask the question, how does that happen?” Mr. Bush said. “It helped that Bill was so gracious.”

He went on to plug his book, “41: A Portrait of My Father,” an ode to the elder Bush, released last year. “It’s important to be a humble winner, and I find that relationship to be very instructive,” he said, referring to Mr. Clinton’s friendship with his father. “That’s why I spent a fair amount of time in Chapter 7 on it.”

POTUSes seem so cool once they are out of office.
