It is superior skills of Trump and his team.
Think of it as medieval warfare
The battle is essentially one on one
The outcome depends on the motivation, training, skill and the excellence of the weapon.
Spartans...what is your profession...?
Review the film clip from the 300 ...where Leonidas meets with the Athenians.

Trump..like Leonidas takes no prisoners....and like Leonidas sports a Mullet.
Now that Trump has thrashed Clinton in debate one, he can afford not to appear in the remaining two, as advised by Giuliani.

'Think of Trump as surrounded by an invisible shield of REACTIVE ARMOUR.
Anything thrown at him is returned with 10 times force.

"I have great respect for the Japanese, but they are very difficult to deal with. For starters, they come to see you in groups of six or eight or even twelve, so you have to convince them all to make a deal. You may succeed with one or two or three, but 12 is more difficult."

Trump will demolish Hillary and her "moderators" in short order.
