Poilievre has no intention of changing the equalization payments, that argument doesn't make sense.
Politics isn't 100% rational. Sympathy for Albertan separatism only reemerged as Harper left the scene, and peaked as disgust with Trudeau reached its peak. Freeland wouldn't have done any better, will Carney? Alberta's premier tried to negotiate directly with Trump to avoid tariffs on energy, which earned pushback by the Liberals. Alberta in turn warned the Federal government not to tax energy exports as a retaliatory measure. If Trump truly aimed to absorb Canada it would have made more sense to drive a wedge between Edmonton and Ottawa.
Conservatives are notorious for selling off parts of our country to foreigners. See the 407. How do you think pierre will hold up to bullying from Trump.
The sale price of the 407 was pretty bad, but it's currently majority owned by the CPPIB. Poilievre has had to battle for years against Canadian media, I think he'd do fine. Trump wants performative action on Chinese money laundering and a few high profile tariff schemes axed, which they should be anyway because they're terrible for your average Canadian consumer.
