Trump is unabashed narcissist. If something goes wrong, it's never his fault, it's always someone else. He's always right, everyone else is always wrong. Everything is about him, if Google finds disproportionate number of negative stories about him, it must be because they're conspiring against him, they're wrong, not him.
He's painfully predictable.
Is extreme narcissism a mental disorder worthy of removal from the office? In this specific case definitely yes, the man would not be able to function in a society if it wasn't for his money, but I don't think it's going to happen. And since Americans seem to be incapable from learning unless we suffer very direct and very dire consequences, it might be best to let it play out until the end. Maybe after everything goes to shit, maybe then the message will stick and Americans finally wise up.
