A Sister Souljah moment is a politician's calculated public repudiation of an extremist person, statement, group or position that is perceived to have some association with the politician's own party. It has been described as "a key moment when the candidate takes what at least appears to be a bold stand against certain extremes within their party" and as "a calculated denunciation of an extremist position or special interest group." This act is intended to be a signal to centrist voters that the politician is not beholden to those positions or interest groups. However, such a repudiation runs the risk of alienating some of the politician's allies and the party's base voters. The term is named after the hip hop artist Sister Souljah.
