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

Joining Éric this week is Christian Bourque, executive vice-president of Léger, to discuss the challenges that a long campaign poses for pollsters. He explains how reduced budgets and an extended campaign period is forcing pollsters to adapt.

Also: the race in Quebec. Can the New Democrats hold on to their lead? Has the return of Gilles Duceppe changed the game? Éric discusses these questions with one of Quebec's most experienced pollsters.
