I think people are quite tired of the harms of a centralized globalization effort - whether from a decentralized cabal or official part of law and official government agreements.
For my evidence I'll reference this top upvoted comment that references actual truths, realities on the ground:
"Does the economist know what time it is? Nationalism is resurgent: nationalist parties now control the U.S. and Italy. Canada seems poised to Poilievre, who has made impassioned appeals to Canadian nationalism. And in Germany, France, and the U.K., nationalist parties have effectively rendered the governing coalitions impotent, even if they cannot yet command a majority. What a time to suggest that Canadians cede their sovereignty to bureaucrats in far-away Brussels!"
