Leo Wise isn’t all that different from a lot of bright, thirtysomething Washington lawyers: He has a law degree from Harvard and spent four years at the U.S. Department of Justice as a prosecutor rooting out corporate crime. He’s had the public service bug forever­ — in high school, he was president of Key Club International. And he’s so polite and earnest that his former Justice Department colleague Colleen Conry, now a Ropes & Gray partner, describes him as “Abe Lincoln with blond hair.”

So why is Wise on his way to becoming one of the least-liked lawyers on Capitol Hill?
