Campaigns for political office frequently employ logical fallacies. Common examples of fallacies used by candidates include ad hominem attacks against the opponent instead of the topic; false dichotomy or false dilemma arguments, in which a limited number of options are unfairly presented with the implication that choice must be made from only these; and the straw man argument, in which the reasoner sets up a weak argument and then knocks it down by oversimplifying the opponent's position and then refuting the oversimplification.
