I'm certain most of you have noticed this, but for those of you who are kinda slow like me...
Trump uses the Jedi Mind Trick. Otherwise known as Neural Linguistic Programming.
When asked how he will fix the economy, for example, he doesn't give you any policy details from which you can draw your own conclusions, he just gives you the conclusions he wants you to walk away with.
To be more specific. He doesn't spend much (or any) time on which tax rates will change and what new rates he'd implemented, rather he says "Your taxes are going to be lower and it's going to be amazing".
So if you're not paying close attention, the feeling you walk away with is "Trump is going to lower my taxes" - even if you don't know how or why that will happen.
The same is especially true for Isis. He doesn't tell you how he will defeat them, or what he would do differently, only that "They will be gone. I will destroy them. It will incredible folks".
Yuuuuge.
