That's... not a thing?

it's pretty clearly associated with factor 4, the effect of the use on the potential market

Looking at this question from the perspective of creators, whose works are often used by political campaigns without permission or consent, the concern becomes how political appropriation of their works impacts the creator’s own right to free expression. During a Congressional hearing on fair use in the context of political campaigns, award-winning Gospel singer and songwriter Yolanda Adams discussed the importance of a creator’s right not to have their speech used to push views or messages they do not support. A song or artist becoming associated with a particular politician, campaign, or political view can adversely affect the marketability and/or value of the original work.

this might be less of a concern with this specific video which seems more parodic in nature, I'm just saying fair use doesn't ever seem to be clear cut
