The religious right in the US - Laurie Taylor talks to Anne Nelson, writer and Adjunct Research Scholar in the Faculty of International and Public Affairs at Columbia University, about her exploration of the way in which the religious right in the US has risen to political power. Who are the Council for National Policy and why does she consider they represent a 'shadow network'? Also Gregory Smith, associate director of research at Pew Research Center in Washington, provides facts and figures on the white evangelical vote.
