These arguments aren't helping matters."Meanwhile, there was more bad news for the singer on Saturday (27.10.12) after she was booed on the New Orleans leg of her tour when she backed US President Barack Obama to win a second term in office.She said: "I don't care who you vote for as long as you vote for Obama. Seriously, I don't care who you vote for ... Do not take this privilege for granted. Go vote."Many of the concertgoers were so furious with her endorsement that they walked out of the gig.
