There's been a huge focus on the president in the last few days as calls for him to stand down as a Democratic candidate in November's presidential race grow. The latest comes from the movie star and crucially Democratic Party donor George Clooney. He says the Democrats can't win if Mr. Biden is the candidate. Well, earlier I spoke to pollster and author John Zogby.
