Being POTUS does not necessarily equate to intelligence. Being electable, at this moment in our media-obsessed country, has less to do with raw intelligence and more to do with eliciting a feeling amongst enough people that they are motivated to vote for you. Trump is all empty branding. He's intuitively and instinctively talented in this area. He understands perception becomes reality as long as you're committed to that perception long enough. Because Americans are, in large part, not very bright. They are programmed consumers of products and content.
He's also talented in being fraudulent. I was reminded a few minutes ago of how his sister filed retirement papers to avoid further investigation into her benefitting, while being a federal judge, from the Trump family's fraudulent tax schemes. And then there is the fake university, the phony foundation, the money laundering, and on and on.
So, yeah, Donald Trump, the man who is a stable genius, who sends threatening letters to every school he attended, yeah, he's really, really, really smart. And successful, too!
It will really be interesting to see what happens to people when they finally realize what an amazing statement the Trump phenomenon is making about their country, about them. Will we care? Probably not. We got shit to buy, after all.
