This week, The House is at the Liberal policy convention in Halifax. Chris Hall talks to participants, MPs, and the new party president about the challenges the Liberals are facing, and the new policies needed to win in 2019. We also ask Barack Obama’s former chief strategy David Axelrod if Justin Trudeau’s “Sunny Ways” pitch will be enough to secure a second win or if he’ll need a new approach and new policies now that the political honeymoon is over.
