This week we look at the US elections and speak to our panel and to voters in New York about what Hillary Clinton means to them. We also talk about whether it makes sense to start the search for the leader of the free world in Iowa, and what is a caucus anyway? Our special guest is Anne-Marie Slaughter, one of America's best-known public commentators, who talks about what is making Americans so fearful, whether the two-party system is broken and the difference it would make to have a grandmother in the White House.
