Donald Trump is the kind of jerk who authentically, genuinely, unabashedly inhabits his own jerkiness. The indifference to reality he’s displayed on the campaign trail is the same indifference he displayed as a businessman, a husband, a boss, and a taxpayer. His narcissism, petulance, and whatever other character flaw you care to choose aren’t under wraps; they’re on view for all to see and hear. In this sense, he truly is the real thing.
Trump’s disregard for propriety, for principles, and for anyone else’s view of the world is heartfelt. As a consequence, his lies have the emotional resonance of truth. And this is precisely what makes him so dangerous.
