I can't understand why repeatedly blaming the woman closest to him for the technical issues that seem to have delayed the show isn't a bad enough reason to not vote for the man. Even if they were her fault, which obv. she's the talent, not the crew, there's nothing but looking like a dick to call her out publicly. So at least he only did that a few times?

Trump was oafish in that.

While her question was combative, Trump is asking to take a job where other world leaders will be combative with him, and this is his chance to show the audience how professional he can be in that situation.

Instead, he acts like a petulant child and berates the woman repeatedly.
