I’ve noticed that myself. But I don’t think it’s because The Donald is unaware of the rhetorical effect he creates.
I’m pretty sure he just doesn’t really care if he’s persuading the crowd or if they agree with him.
It’s probably because after spending a million and a half of his own money, he’s still got about ten billion (more or less) reasons to tell everyone to **** off.
Yeah, his speaking style and manner is appalling. You want someone ‘slick’? ;^]
But he could try harder, you’re right.
You do, or don't think it is?
I'm being sincere.
"Don't" seems incongruous with the rest of your post.
