Donald Trump , a world-class narcissist with no interests beyond self-promotion and money, in all likelihood entered the presidential race as a promotional gimmick. That’s what former advisers suggest, at any rate. It’s the only thing Trump has ever been good at — self-promotion, that is. His actual real-estate business cratered, as the 1995 tax returns show. A string of businesses (vodka, airlines, mortgage brokerage, football team) all failed. But through it all, Trump’s insatiable desire for publicity and expertise in media manipulation — from exaggerating his wealth to assuming the identity of a PR man — fueled his image and generated a certain level of wealth (less than advertised, but still).
