When Trump was president, if you watched Trump, The Live Show, you had the full uncut Trump. If you just read the NYT reports or watched later clips, his act was always cleaned up. Any gibberish quotes were paraphrased, with, quite often, the journalist telling you what they thought he meant, not what he plainly said, without making the interpretation role clear.
"Gaffes" are normally VERY EXCITING except when they aren't.
