CTVNews.ca's Michael Stittle and Nanos Research's Nik Nanos take a look at where each federal opposition leader stands going into a potential election later in the year. It's the challengers episode! (Complete with summer homework assignments.)

Conservative Leader Erin O'Toole will need to perform a balancing act between keeping his party united in the West and gaining some additional seats in Ontario. While NDP Leader Jagmeet Singh will need to take advantage of some of the goodwill he's earned from Canadians. Listen to the show for all the rest.

Finally, in our 'Upshot' segment, Nanos explains why the Liberal numbers might be 'overpriced' and why a win in a snap election might not be a sure thing for the party.
