shyster - 1.unethical person: an unscrupulous person, especially a lawyer or political representative.<quoted text>
A person, esp. a lawyer, who uses unscrupulous, fraudulent, or deceptive methods in business.
(If the "shyster" was white and looked smooth and slick like Mitt Romney; you'd have said he was a clever businessman, afterall, Mitt never created a thing, all he did was fk people over to get rich)
Obama and his corrupt Chicago cohorts would fall under the latter category.
