Which argumentation technique relies on opposing a candidate through unfounded allegations about their character?

The argumentation technique that relies on opposing a candidate through unfounded allegations about their character is known as Ad Hominem. This term refers specifically to a fallacy that attacks the individual rather than addressing the merits of their arguments or the issues at hand. By focusing on the character, motives, or actions of the person rather than their qualifications or proposals, this technique seeks to discredit the opponent in a way that is often misleading and unsubstantiated.

Using Ad Hominem can divert attention from the actual topic of debate and can manipulate the audience's perception based on emotional responses rather than logical reasoning. This tactic is common in political discourse where candidates may face attacks intended to damage their reputation rather than challenge their policies or ideas.
