Sarah Palin needles Barack Obama, Republicans in speech

Former US vice presidential candidate Sarah Palin took centre stage to speak before conservative activists on Saturday, needling President Barack Obama and even fellow Republicans. "We don't have leadership coming out of Washington, we have reality television, except it's really bad reality TV, and the American people tuned out a long time ago," Palin told the Conservative Political Action Conference, known as CPAC, held near Washington.
