There is next to 0 appetite in Quebec for libertarian government. In about 65 out of 75 ridings, it disqualifies you before the race even begins. Thinking that Bernier can "deliver" quebec in these conditions is laughable.
In Quebec, Bernier is known for the Joe Louis incident, the HA girlfriend, and the secret document fiasco. Politically, he's a walking catch-22: either he promotes a right-wing libertarian platform with which nobody agrees in Quebec (except for a few ridings in the south and around Quebec city) or he keeps it low profile and stays known for the aforementionned fiascos. If you don't believe a liberal campaign wouldn't bring back the videos of this guy insulting members of our armed forces with his f... joe louis I don't think you've been following the news the last 10 years. The only road to victory is a massive amount of ridings in ontario.
The reason I believe this guy will never win is because I know him personnaly. His dad was a smart guy.
Anyway, if I was at the pcc, I'd be preparing the 2023 elections, not the 2019. By then Trudeau will be a washed-up has-been, voters will be tired of his whole government, the NPD will be taking votes from them; it'll be the right time to beat them. But unless someone really drops the ball in the next 2 years, it'll be really hard for the conservative to win the election. And it won't happen with quebec ridings, which I believe Bernier can't deliver anyway.
