QUÉBEC CITY—Spare a moment of sympathy, if you can, for Quebec Premier François Legault. As I drove by his office here this week, I could not help but feel sorry for him. By his own admission, he had a “bad day” last week. In his attempts to make Quebec more in his own nationalist image, he and his Coalition Avenir Quebec (CAQ) party have stumbled badly over three delicate dossiers: immigration, education, and anglophones.
