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

The Conservative leadership race has been shaken up by the departure of Jason Kenney for a bid at provincial leadership in Alberta. But a new name was added to the list of candidates this week when Tony Clement threw his hat in the ring.

So what do this new entry and high-profile exit mean for for the leadership campaign?

Alberta MP Jason Kenney has opted to head back home to try to win the leadership of the Progressive Conservatives, unite the right in that province, and defeat the New Democrats in 2019. It's a tall order.

But his decision to leave federal politics has made winning the leadership of the Conservative Party of Canada a little easier for the contestants already in the race: Ontario MPs Michael Chong and Kellie Leitch and Quebec MP Maxime Bernier.

And now Tony Clement. The Ontario MP has been here before — he ran for the party leadership more than a decade ago after the merger of the federal PCs and Canadian Alliance. He also ran for the leadership of the Ontario PCs in 2002. Both attempts were unsuccessful.

So will it be third time's a charm for Clement? And with Kenney out, who thinks they can fill the space Kenney would have occupied had he run for the federal party's top job?

Joining host Éric Grenier on this week's episode of the Pollcast are Conservative insiders Tim Powers of Summa Strategies and Chad Rogers of Crestview Strategy to break it down.
