I will agree that Trump's mic will be cut. That's going to happen, multiple times.
Not because of a conspiracy against him, but because he can't be clear and concise. He rambles on and jumps topics. He'll get reprimanded for the same reasons- he can't stay on target. He'll wander all over the place, get told to stay on topic, and then go over his time.
He'll get interrupted for the same reasons.
And the questions will look hard because... for the same reasons! He can't stay on topic and wanders from topic to topic.
He's going to do poorly because he lacks focus and discipline.
