On a segment that took an extra two-weeks to air — it was postponed following the earthquake in Haiti — “Nightline” anchor Terry Moran profiles the two Lou Dobbs: “Angry Lou… and affable Lou.”

Dobbs, a long-time CNN anchor who recently left the network, tells Moran that he has at times been “enamored” with the idea of running for office and also admits that he’s tried to improve his standing with Hispanic-Americans: “I don’t know that I’m ‘popular,’ but I’m trying. I hope I will be, by the way, because I intend to be part of the solution.” When asked if he’s changing his tune on immigration, Dobbs said, “Hell yes I’m changing my tune. Absolutely.” Video:
