Clearly, you don’t get it. Trump doesn’t manage it at all - that’s the beauty of the whole thing. It’s just Americana, pure and simple listening to someone saying what they are saying but can’t get heard, or if heard, listened to. If you don’t like that, shame on you. The three little ones were adorable, to boot.
Trump (or, rather, the Trump campaign) doesn’t manage his campaign rallies? How naive are you?
