What aspect of Presidential debates is noted for being less formal?

The aspect of presidential debates that is noted for being less formal is the debate format. This refers to how the debate is organized and conducted, which can vary significantly from one debate to another. For instance, some debates may use a more relaxed format that allows for greater free exchange between candidates, informal interactions, and even audience participation, creating an atmosphere that feels less structured than traditional formal debates.

Conversely, other elements such as the structure of questions, candidate attire, and audience presence typically adhere to more established norms. The structure of questions tends to follow specific guidelines aimed at eliciting detailed responses from candidates, while candidate attire usually aligns with formal expectations to convey professionalism and seriousness. Audience presence can add a layer of formality but also contribute to an environment of engagement and interaction. However, it is the debate format itself that distinctly embodies a range of formality levels, allowing for more or less rigidity based on the rules set by the organizers of the debate.
