She’s living in a political world. Madonna may have misjudged her audience Saturday night in New Orleans. The pop godmother triggered boos and a small walkout when she said, “I don’t care who you vote for as long as you vote for Obama.” Never one for avoiding controversy, Madonna recently drew criticism for showing a swastika on a politician’s head in a video during a Paris show. She also leapt to the fore to support a Pakistani teenage girl shot by the Taliban. What can you do? She is a political girl.
