In the last 2 elections more Canadians voted for the CPC than the Liberals. Or the NDP and Greens combined.
The NDP and Greens are losers that most Canadians think are filled with naive idealistic nutbars.
Canadians don't like nutbar idealogues like the Liberals, CPC, NDP, and Greens. Quebec likes french/Quebec politicians, so Trudeau wins despite losing the popular vote to the CPC. And people don't even like the CPC, they just dislike Trudeau even more.
Your plan to keep the CPC being a bunch of conservative nutters is a loser plan. Most conservatives and leftists are morons and nutters and irrational ideologues. Most Canadians are reasonable and don't want closet racist bible-thumping gay-haters running this country, nor do they want the virtue signaling beta cuck wusses we have now. Guys like Trudeau and Scheer are out of their minds.
