If Mangolini weren't such an idiot, he wouldn't have revoked the de minimus exemption (meaning orders under $800 were exempt from the tariffs), then his rube followers would never have noticed anything.
I’m not totally convinced that a huge swath of trump voters ever heard any alternatives to the propaganda that lead them to believe tariffs=good.
Like i imagine a ton of them are structurally isolated from hearing alternatives the way social media and television works
