It's not a wasted vote though. Elections Canada provides funding to losing political parties based on the number of votes, I think it's a certain percentage for every 1000 or 10000 votes. I learned this when I was on my local EDA for the PPC's first election run.
Personally, I promised myself a long time ago that if Poilievre was leader, I would give the cons a single last chance. It will be him who decides if I ever vote team blue again, largely on if he follows through with repealing all of Trudeau's gun bans, which is issue number one for me.
I've spoken in person with Bernier himself in regards to some firearms things, and while I don't think he was jerking me around or pulling my chain, I really didn't like his answers on the matter.
