Democracies are divided. So divided, in fact, that Tom Carothers - Co-Director of the Democracy, Conflict, and Governance Program at the Carnegie Endowment for International Peace - wrote an entire book on it.

If someone asked you to think about a democracy in trouble, chances are the United States comes to mind. And not without reason; the current presidential race is shaping up to be a re-match between two deeply unpopular candidates - one of whom poses a threat to the very institution of Western democracy.

The reality is that democracies everywhere are struggling. Carothers' book provides insights into the challenges facing democracies in Europe, Asia, Africa, and South America. We talk with Tom about what and who is responsible for this troubling trend in democracies.
