Political Weirdos

It's unpopular now, so they'll float the idea of it being a joke or just rambling of a certain "leader". That way they can gauge how many are actually accepting of the idea, and slowly tune the narrative while propagandizing it to make the message more acceptable.

And there's the sure narratives. Canada and Mexico are cheating the US. Trade is not balanced. Etc Throw in some tariffs and blame Canada/Mexico/etc even more for the increased prices. Shift the public opinion while cutting back education and growing the narrative that America is the victim. Then when resources also get more scarce, suddenly a little "liberation" becomes an acceptable solution...
