The CBC Election Pollcast, hosted by CBC poll analyst and founder Éric Grenier, explores the world of political polls, their influence on the media and the trends they are showing.

Joining Éric on this week's podcast is Christian Bourque, Executive Vice-President at polling firm Léger, and David Akin, Parliamentary Bureau Chief for Sun Media.

What trends have become clear at this stage of the campaign? Can the New Democrats hold on to their lead in the polls? And what about the electoral chances of the Bloc Québécois and the Greens?
