In what scenario is the fallacy of Ad Hominem likely to arise during a debate?

The scenario where the fallacy of Ad Hominem is most likely to arise during a debate is when a candidate is criticized for their character rather than their policies. This fallacy occurs when the focus of the argument turns personal, attacking an individual's character, motives, or traits instead of addressing the actual arguments or policies at hand. By diverting the discussion from the substance of the debate to irrelevant personal attributes, the effectiveness of the argument is undermined. This tactic is often used to discredit an opponent, making the audience less receptive to their actual arguments, thus showcasing the Ad Hominem fallacy in practice.
