Because he's push American-style GOP politics and that has destroyed America and taken them to the brink of civil war.
He hasn't even got the job yet and he says he's going to commit a scandal on par with the Justice Minister interference scandal by wanting to interfere with the independent BoC because he claims they don't understand economics, but he himself pushed Bitcoin, which is now worth 25% of what it did when he pushed it. Still on the topic of economics, he wants to reverse a tax that results in low-income earners getting a net profit because he claims it causes low-income earners hardship.. He wants to expose the internal workings of our intelligence apparatus to everyone including groups working to subvert Canada, against the advice of the members of his own party who say it's a horribly idea. Like Trump, he's skirted supporting the most toxic segments of our society including pushing nonsense conspiracy theories to egg them on. Like Trump, he pushes misinformation and dismissed expert opinions as "gatekeeping", which if actually a form of gatekeeping because it's him claiming he has a secret knowledge others don't.
I could go on. But here's the thing: Justin Trudeau is a clown who, despite his scandals, has caused no real lasting damage to the Canada but is largely just an embarrassment. The only people who think otherwise are the COVID clowns, the "woke" haters, the anti-WEF conspiracy theorists, and the Poillievre/Trump/MAGA cultists. Pierre Poillievre has already done harm to Canada, though not real and lasting, but has the possibility to and things he's already said he would do (like exposing our intelligence apparatus) definitely have high risk to. Like at how Trump/MAGA cult members have tried to completely destroy democracy and install their king against the electorate. That's the road Poillievre has already started taking us down.
I'll take blackface dancing clown over actual threat to our democracy every day. But I'm hoping another option emerges.
I know from your post history you don't think so and you're right on board with what PP is selling, including the conspiracies. This entire post was a waste of time where you're concerned because you disagree with all that, you think Trudeau has given away our democracy and destroyed our economy and society. And the fact that Poillievre has fueled those views and has given your nonsense a legitimate voice is exactly what makes him worse and more dangerous than Trudeau. But I hope some people on the fence can still be swayed which is why I replied anyway.
I hope our checks and balances keep him at bay. But I don't think they will. Our system isn't strong enough for that. The PMO has far more power over Canadian affairs than the Office of the President has over US affairs. If PP wins, I think it spells disaster for Canada. Whereas Trudeau mostly spells embarrassment.
