What is the difference between giving an oral presentation of your how to essay and making a video of it ?

The difference is how you are actually presenting it. In a video you can not make the eye contact and the "Audience interaction" as you would in an oral presentation. In a oral presentation you are actually there and can actually make the "audience" be more invested in what you are saying. You can not do that to well in a video.

from the political point of view it could be said that the candidate   is an effective speaker because she takes a strong position on the issue. it is an open discussion but probably she is making a presentation and can choose which subjects she wants to address. she is very likely to attain her aim which is to convince voters to accept her proposal.
