Here is a hypothetical. Clearly Bernier is the most right wing, libertarian among the bunch. He has a lot to say about liberalizing gun control, cutting down the CBC, changing equalization, and so on. Say that those who like Bernier vote him number 1, and those who are more centrist rank all of  Michael Chong, Erin O’Toole, Lisa Raitt, and Andrew Scheer higher than Bernier.  Then if the latter four candidates have more support collectively than Bernier, ONE of them will certainly win. So, guess who will be targeted in the next debate.
