Following the third and final US election debate, we're looking at the economic challenges dividing the candidates. White working class men, for example, are said to be siding with Trump. We hear from our economics correspondent, Andrew Walker, about why some of them are struggling despite an improving jobs market. We also hear from Angus Deaton, a Professor of Economics at Princeton University, about what he thinks the real economic problems are facing blue-collar Americans (it's not globalisation, he says). Also, our regular commentator James Srodes says: don't place too much faith in reports of a strong Clinton lead in the opinion polls. This year's volatile surveys indicate that, more than ever, the pollsters have lost track of the true sentiments of US voters.
