Senator Larry Craig's Guilty Plea those calls are likely to go louder now. Reporter: Judy smith helped him make a dignified exit. Therefore it is with sadness and deep regret. Reporter: He decided not to run for re-election. Judy smith. She succeeded, as much as you can when a man pleads guilty to soliciting gay sex in a bathroom. Reporter: She did. But his career was still down the toilet. So, on our scandal score sheet we have career ruined. Cost -- $200,000 in legal fees. Marriage -- intact. Reporter: Next up number six on our scandal countdown mark sanford, erstwhile governor of south carolina. Our tale begins with a mystery. Sanford's wife of 20 years, jenny, had no idea where he was. No one did. I haven't talked to him, and his office hasn't contacted me. There was a watch on mark sanford's whereabouts that only is akin to boy trapped in well, or miners trapped in a mine shaft. Reporter: Then his staff came up with an explanation. South carolina's governor, gone for four days without contacting his office or his family, finally checks in today. The spokesman says governor mark sanford went on a hike along the appalachian trail. Reporter: But the very next day a reporter spotted sanford at atlanta airport getting off a plane from argentina. Busted. His office said he was off "hiking the appalachian trail," but in reality he was in argentina having sex with his mistress. Tomato, tomato. Reporter: How would he explain this to his wife jenny? I thought he loved me in his own way, which is not a warm, bubbly way. But i, I thought he loved me. Reporter: Just hours later, sanford opted for the all-out confession route. Let me first of all apologize to my wife jenny and our four great boys for letting them down. That speech was the most jaw-dropping thing I've ever seen. I have been unfaithful to my wife. I developed a relationship with a -- what started as a dear, dear friend. Recently over this last year it developed into something much more than that. So the press conference was one of those amazing television moments where you were actually watching somebody sort of melt down, in front of your very eyes. He fell in love! I spent the last five days of my life crying in argentina. Wait, is that an "evita" reference? It was awful for me to watch my husband come back and pine about his soul mate and days spent crying in argentina. The odyssey that we're all on in life is with regard to heart. I had never heard him speak about love in that manner before. We had both had more of a practical view of what love was. Reporter: Jenny was watching on tv. Live. Not standing by her man. He'd gone too far. It was awful from the political standpoint, because he really should have -- should have stopped talking at a certain point. I mean, it was awful on so many levels. There's a certain irony to this. I think that she gave him, obviously, something that i didn't, or she made him feel things that obviously I didn't make him feel. But in many respects, it was kind of a fantasy relationship. Reporter: They divorced. Mark paid an ethics fine for using state funds to fly to south america to have sex with his miss stress tres and apologized to anyone who would listen. More recently, I have experience how none of us go through life without mistakes. Reporter: Sanford's score sheet, marriage, over. But he's now married to the mistress. Career -- back on track. He was just elected to the u.S. Congress.
