The group of people standing behind politicians and other public figures while they give speeches are typically called "staffers," "aides," or "supporters." There are a few reasons why they are often present during public appearances:
Symbol of Support: Having a group of people behind a public figure can visually symbolize that the individual has a team of supporters and allies. It can help create a sense of solidarity and demonstrate that the person has a network of people who back their ideas and leadership.
Visual Impact: From a presentation perspective, having a group of people standing behind the speaker can make the scene more visually engaging for the audience. It adds depth to the image and may make the event appear more substantial.
Political Message: In political contexts, the individuals standing behind a politician may represent specific demographics, constituents, or organizations that the politician seeks to highlight as part of their message. It can be a strategic way to showcase a diverse and inclusive coalition.
Event Organization: In large public events, the people standing behind the speaker may include event organizers, security personnel, or other staff responsible for managing the event smoothly.
Cue for Applause: In some cases, the people behind the speaker may be strategically placed to initiate applause or cheer at appropriate moments during the speech, encouraging the audience to join in.
Media Presence: The presence of a group of people behind a public figure can also create more engaging and attention-grabbing visuals for the media, which might lead to increased coverage and exposure for the event and the speaker's message.
It's important to note that the specific reasons for having people stand behind a public figure during speeches can vary depending on the context, event type, and the intended message. Not all public figures or politicians choose to have people standing behind them during speeches, and it's ultimately a matter of personal preference and communication strategy.
