The CBC Pollcast, hosted by CBC poll analyst Éric Grenier, explores the world of electoral politics, political polls and the trends they reveal.

It was a year for change. A new government getting settled in Ottawa, a new president on the way in the United States, and two opposition parties searching for the next leaders to take on Justin Trudeau.

But if there was one lesson to take from 2016, it is that politics can be unpredictable.

What were the successes of Trudeau's first full year in office? What were some of his failures? What has the Liberal government's new approach and the election of Donald Trump taught the media about what matters most to people outside of the political bubble in Ottawa or Washington, D.C.?

And what to make of the candidate-less NDP leadership race and the cavalcade of contestants in the running for the Conservative top job?

Joining host Éric Grenier on the last Pollcast episode of 2016 are Susan Delacourt, columnist for the Toronto Star and iPolitics, and Althia Raj, the Ottawa Bureau Chief of The Huffington Post Canada.
