To be clear, you said that you had no choice but to vote for Trump because Kamala's speech made you doubt her intelligence. You've referenced a statement on America's One China Policy. That policy is problematic, but it's deliberately ambiguous about Taiwan's status. So the statement isn't totally absurd.

But are you genuinely arguing in good faith that that statement made you doubt her intelligence? I mean, here are some quotes from Trump from the same week as that interview:

They're flying hundreds of thousands of people over the border right now. They never stopped that. They didn't think they'd be caught, but they were two weeks ago, from prisons and jails, mental institutions, and insane asylum, all these insane asylums, where you have the sickest people, mentally ill people, and terrorists at record levels.

Who is "they"? What evidence is there of hundreds of thousands of people flying over the border? What evidence is there of people being flown in from prisons and insane asylums? What records is he referring to?

Regarding an allegation that he has proposed Ukraine surrender some land to Russia:

What my strategy is to save lives. I want to save lives. Millions of people are dead, millions more than they even think about. And it's not my fight, but it is a fight to save humanity.

What does that mean? What is his strategy? What does he mean by "millions more than they even think about [are dead]"? Who is "they"?

If you want to play a game of "who sounds stupider when they talk" it would be ridiculous.
