ReTard n. Portmanteu of "Republican" and "retard". Someone who, intoxicated by an assumption about being knowlegable and right about politics and economics, forgets that they need to get actual real ordinary people to support them if their agenda is to be advanced. Often but not always middle class, easily led and with poor insight to society's problems, and naive about the mechanics of politics and utterly ignorant about how power actually works.
