To be fair, in the seconds leading up to that remark (again consult video above) it was nothing but word salad. Something about "the Puerto Rico I am .... my home state of Deleware..." - like he was about to claim he was from Purto Rico and then brain farted back to Deleware.
So, maybe the teleprompter had a really good zinger on it, one that wouldn't upset the media so much, but he just forked it up because, for a moment, he truly thought he grew up in Puerto Rico.
Either way, Trump was being called Hitler for years. Then, he almost got a bullet through the head and everyone thought maybe the BS should be toned down a bit. But, what's the October surprise? He's Hitler again!
What kind of a person would elect Hitler?
Being called garbage is nothing.
