Stephen Colbert started off Wednesday's Late Show with an explanation of Ash Wednesday and a struggle over whether he could break the late-night rules by skipping the monologue and just running to his desk to discuss the New Hampshire primaries. The winner of the Democratic primary, Sen. Bernie Sanders, walked on to tell him he could, and to provide comic relief. Later in the show, when Sanders sat down for his interview, Colbert asked him why he thinks he crushed Hillary Clinton among young voters.
