Did Trump accidentally save Canada's Liberals?

For the last couple of years, it has looked a foregone conclusion that Justin Trudeau's Liberal Party was going to go down in flames at the next election, and Trump-aligned Pierre Poilievre would rise in his place, bringing the MAGA revolution north of the border. But Trump's jibes, his threats of 25% tariffs and his desire that Canada should become the 51st state, have thrown all the normal political logic in the air. This week, the Liberals topped the poll again. Has Trump, inadvertently, buried his would-be torchbearer just when it most counts?
