It doesn't matter who the CPC elects as leader, it will lose the 2019 election. The party needs to learn from 2015 and it needs to rebuild with new policies and a new attitude. My guess is that the Conservatives have to go through an extended period in opposition as did the Liberals before them and a couple more changes of leadership before they become relevant again. Bernier won't be able to implement any of the stuff he's talking about because he won't be PM. Also, it is not enough for an incumbent government to be unpopular, there has to be a credible alternative - the Ontario Liberals would be long gone from power if not for Hudak and Brown seems to be invisible.
