From a story on politico.com by Ian Ward headlined “Ralph Nader Thinks People Aren’t Paying Attention to His Progressive Agenda”:

For over 50 years, Ralph Nader has served as the self-appointed conscience of the American left, the safety inspector of a Democratic Party that, in his judgment, is too corrupted by corporate influence and partisan hackery to pay attention to the problems that really matter. His invectives against mainstream Democrats — combined with lingering resentment over his ill-fated presidential campaign in 2000 — have relegated him to the margins of Capitol Hill, a sidelines position that he relishes as inverse proof of the righteousness of his crusade.
