In short, a politician's aide is his or her right hand. Behind every successful politician is a terrific aide. Political aides make themselves indispensable by specializing in an area like transportation or technology.

They then advise their politicians as to how to garner votes and even how to minimize the damaging effects of scandals and other fiascoes.
