So the most favorable interpretation of his words is that his supporters are delusional? What is their interpretation of "fix the country"? Because if it does not involve changing the constitution (a very tall order) then every single thing he does can be undone with the same effort by the next democratic president. Surely these people know that, right? How could they possibly believe that he will magically "fix the country" so they don't have to vote any more, unless they anticipate that he means something permanent?
Because they don’t take things so literally.
I’m not trying to be flippant, that’s genuinely the answer to your question. Trump is literally being dramatic and funny by putting it like that. And you’re taking the bait and missing the joke.
I know I sound like the enemy and I dislike including this paragraph: But keep in mind, I can’t stand Donald Trump and didn’t vote for him.
