In political campaigns, advertising and propaganda always try to influence the audience in favor of a candidate or against the opposite candidate. The messages created by propaganda and advertisement are biased with information that wants to appeal to the emotion of the audience, not the mind, the reason. Advertisers and PR people develop messages using Pathos, or the appeal to the emotion instead of Logos, the appeal to the reason using facts or figures.
