Bernier knew that Scheer didn't have a hope in Hell in 2019 (and the most recent polls before Maxime bailed underscored this). That's why he did what he did. You're deluding yourself thinking that Scheer had a chance.
The TMX and the NAFTA disasters will hurt the Turd in the coming election but Jagmeet Singh will be siphoning those votes.
As gun owners we all need to now be supporting Bernier all the way. He is our only voice in the federal government. Remember that he lost the Conservative leadership race by a fraction of a fraction of 1%. This means that his potential support is likely still there.
Bernier defeating the Turd in 2019 is extremely unlikely (and I really do believe that Max already knows this). But the Lefty vote in the next election will likely be even further split between Turdeau and Singh by current Liberals who feel that Turdeau isn't destroying the country fast enough. This means that, with enough of real Conservative support behind him, Bernier might have a realistic chance of being the official opposition in 2019 and perhaps the Turd will have only a minority government. This is at least something that we can justifiably hope for.
Support Bernier now and let's focus on 2023.

(If I'm wrong and Bernier doesn't have the support that he thinks he has then Canada is truly lost. If that is indeed the case then let's know now.)
