Because he does not know what he is talking about.
He keeps saying things like:
“Nobody respects women more than I do.”
“I am the least racist person you’ve ever met.”
“I am the only one who can fix this.”
How does he know?
How does he know, for example, how much I respect women? He doesn’t. He makes empty statements for effect. That’s not facts. That’s drivel.
He doesn’t know what he is talking about.
He is a salesman, full of bullshit, but hits all the emotional buttons of other bullshitters — they don’t expect him to tell the truth. Like two drunks at a bar deluding themselves they are smart and sexy when they are tiny-dicked, fat dumbasses too stupid to realize it. To them, Hillary is a ball-breaking ex-wife who sees through their bullshit.
