ABC's Good Morning America, trying to overtake NBC's Today to win the morning ratings crown, has scored a big "get" by landing embattled Tour de France champ Floyd Landis for an interview that aired this morning (Monday). He appeared to be changing his defense strategy by stating that he could not explain how two tests showed elevated levels of testosterone in his system. "All of these reasons that have come up we need to forget about that and let the experts figure it out," he said on the program. The interview was certain to boost GMA's audience -- and thereby, its ratings, which have inched closer to Today's in recent months.
