> What the average voter hears: I don't care about any of that. Prices were lower under Trump and he's a businessman, so I'll vote for him so prices go back down.
Yes, and critically: "I trust Trump when he says it's Biden's fault, so I'll vote for him."
It doesn't matter how correct the interlocutor is if the average voter doesn't trust them. Unfortunately, most people place trust in people who appear sincere and unrehearsed, which is the opposite of how much politicians behave, where a "starched, bland, rehearsed" style is traditional. Trump is improvised and chaotic, which people mistake for genuine and trustworthy.
