grifter

A con artist; someone who pulls confidence games; a swindler, scammer, huckster, hustler, and/or charlatan.

We're all grifters. So we sell each other out for a nickel.

That was the train the drunks and the sinners rode—the gambling men and the grifters, the big-time spenders, the skirt-chasers, and all the jolly crew.

A manipulator or otherwise generally corrupt person who "games" a system, group of people, or other entity for selfish gains; especially of a political "sell-out" perceived as lacking integrity.

The latest act in the Madness of King Donald drama playing globally on every channel underlined the increasingly delusional world the anti-hero inhabits, his fantasies fed and indulged by a cast of sycophants, lackeys and straight grifters, all in it for what they can get.
