Watching “Dancing With the Stars’ ” results show Tuesday was a bit like watching “The Karate Kid” all over again. Despite a badly injured leg, Daniel LaRusso… er, Ralph Macchio … took his crane stance once again and knocked competitor Romeo out of the running for the coveted mirror ball trophy, leaving a look of complete shock on judge Carrie Ann Inaba’s face. But this time, the (temporary) victory wasn’t based on the performance. It was all about the fan base.
