Those Canadians who do “blame Canada first” for a trade war that Trump, and Trump alone, started, to say nothing of his boorish talk of annexation, are not many, but they are disproportionately Conservatives — even though there precious little that is conservative about Trump and his policies. In reaction, like the Reagan Democrats of 40 years ago, there are now Carney Conservatives, voters who might otherwise vote Tory but prefer Carney to stand up to Trump. Poilievre, by shutting down Jivani, is alert to that.
