The succubus is a mythological, evil creature who seduces men and steals their health -- and eventually their lives -- through repeated contact. The male version is the incubus, but "succubus" just sounds better :)
With the stuff that comes out of his mouth, it's not so hard to believe that this wants-to-be-president is a variation on the succubus theme, seducing the masses with his hate, vitriol and mistruths. And if we continue to allow him a platform upon which to speak, it's not so farfetched to think that he'll whittle away our health and lives, one lie at a time.
This extension is a gentle reminder that whenever you come across his name to remember what his ambitions and intentions truly are: ruthless and unscrupulous power, not the desire to effect lasting change that'll benefit the majority.
