1993 Chrétien attack ad

During the 1993 Canadian federal election campaign, the Progressive Conservative Party produced a televised attack ad against Jean Chrétien, the Liberal Party leader. The ad (sometimes referred to as the "face ad") was perceived by many as a focus on Chrétien's facial deformity, caused by Bell's palsy. The resulting outcry is considered to be an example of voter backlash from negative campaigning.
