The issue is that the descriptor/ name "Maple Maga" fits a meaningful constituency/ voting bloc within the CPC tent. Any meaningful discussion of Canadian political dynamics needs to address the existence of the Maple Maga* camp no different than the Socon's, Red Tories, Blue Grits, Labour movement, social justice movement etc. etc.
* my loose definition - those whose political and world views are aligned with MAGA and shaped by the reactionary pro-Trump infospace rather than a set of ideals within the traditional Canadian overton window
I've also seen it used to describe the populist/reactionary bent that the CPC has taken trying to mimic the MAGA methodology and style and apply it to their own messaging, but I don't think that use is as accurate
