Definition of "narcissistic"

Anyone who goes into a voting booth on November the 8th and comes out saying, “I feel a hundred percent great about what I just did in there!,” is either lying to themselves, or did something unspeakable in that booth! And that means, as uncomfortable as this is, everyone has to own the floors of whoever you vote for, whether they are a lying handsy narcissistic sociopath, a hawkish Wall Street-friendly embodiment of everything that some people can’t stand about politics, an ill-tempered mountain molester with a radical dangerous tax plan that even he can’t defend, or a conspiracy-pandering political neophyte with no clear understanding of how government operates and who once recorded this folk rap about the virtues of bicycling.

Because narcissistics cannot handle failure, they will take great lengths to avoid risks and situations in which defeat is a possibility.
