Who cares? And I say this a member of the CPC.

Fight amongst yourselves all you want, but the real challenger to Trudeau is Jagmeet Singh, https://en.wikipedia.org/wiki/Jagmeet_Singh. Neither Scheer, nor Bernier, will beat Trudeau, but Singh will. To be slightly disrespectful, he is Jack Layton in a turban, and Jack Layton, turban or not, will win the day.

Go strongly Jagmeet, and get rid of this Trudeau boy!
