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

When Peter Julian, an MP from British Columbia, stepped down as NDP House leader to explore a bid for the party's leadership, he immediately became the front runner.

That's because no one else has expressed any interest in the job.

Since Tom Mulcair's leadership was rejected at the NDP's convention earlier this spring, the race to replace him has yet to start. Even Julian has not officially thrown his hat into the ring yet.

But more names can be put forward as potential candidates, including current MPs Niki Ashton, Charlie Angus and Guy Caron. Jagmeet Singh, an Ontario MPP, has also been mentioned as a potential contender.

The campaign will be a long one, as votes will be cast throughout October, 2017.

Joining podcast host Éric Grenier to discuss the lack of candidates in the race and the list of names that could soon emerge are NDP insiders Sally Housser of Navigator and Robin MacLachlan of Summa Strategies.
