There's enough worry about Canadian sovereignty and enough people who aren't maple MAGA idiots/grifters but don't immediately ignore what Trump says that, if they don't think about precedent that much, this could swing.
I don't really know or care what Trump's intent was, even while I have some guesses, but I do know it's being used as a talking point in the Conservative propaganda machine. "Lol, you think Carney's going to defend our interests, but Trump just endorsed him. Hope you like being the 51st state. If carney wins, Canada loses. WEF, Ghislaine photo, Axe the Tax, etc." The gambit is that all of this convinces more undecideds to vote Conservative than Conservative voters to vote Liberal (or NDP, or Green, or Bloq, but you get my point).
You and I, and I hope enough others, see through this particular tactic. But coupled with points like "Carney said he'd get rid of the carbon tax and GST on homes - those were PPs ideas", there's enough going on that I could see people getting swung. No one is truly immune to propaganda, and the machine do be churning.
I was very sad, and very self-isolating for a long while. This even translated to online interactions - always lurked and never posted, because really what did I have to say that anyone gave a shit about?
Started to feel a little less sad, and talk with people online a bit. The walls didn't necessarily tumble, but they started to crack.
So here I am, speaking though Cracks_InTheWalls. Now, people still don't give a shit about that, but in turn I don't about that, which IMO is a significant improvement from where I was.
