Jimmy Carter ran as a reformer who was "untainted" by Washington political scandals, which many voters found attractive in the wake of the Watergate scandal that had led to President Richard Nixon's resignation. Ford, although personally unconnected with Watergate, was seen by many as too close to the discredited Nixon administration, especially after he granted Nixon a presidential pardon for any crimes he might have committed during his term of office. Ford's pardon of Nixon caused his popularity, as measured by public-opinion polls, to plummet. Ford's refusal to explain his reasons for pardoning Nixon publicly (he would do so in his memoirs several years later), also hurt his image.
