If investigators discredit a politician is the politician likely to get reelected to vote out of office

A politician who is under investigation runs the risk of having his or her reputation ruined. To "discredit" someone is to defame them, or to destroy the trust that other people have in that person. Because a politician is meant to safeguard the interests of the people he represents, a lack of trust is often catastrophic to his or her career. Therefore, a politician that is discredited by investigators is unlikely to get reelected, and would most likely be voted out of office.
