the ad hominem is a fallacy of relevance where someone rejects or criticizes another person’s view on the basis of personal characteristics, background, physical appearance, or other features irrelevant to the argument at issue.
An ad hominem is more than just an insult. It’s an insult used as if it were an argument or evidence in support of a conclusion. Verbally attacking people proves nothing about the truth or falsity of their claims. Use of an ad hominem is commonly known in politics as “mudslinging.” Instead of addressing the candidate’s stance on the issues, or addressing his or her effectiveness as a statesman or stateswoman, an ad hominem focuses on personality issues, speech patterns, wardrobe, style, and other things that affect popularity but have no bearing on their competence. In this way, an ad hominem can be unethical, seeking to manipulate voters by appealing to irrelevant foibles and name-calling instead of addressing core issues
