I don't know I don't really listen to US congressman or senators speak, I only stumbled upon this because it's posted here, but if you can find examples of others dumbing themselves down for their constituents to this extent you can show us an example. This case is pretty blatant imo because the participants not only threw in some random hip hop culture expression which would be bad enough, they actually both did a full transformation into ghetto Shaniqua in an instant, changed their voice, their tone, their pattern of speech, just went full Dr Jekyl Mr Hyde in an instant, it was just bizzare to listen to.
Also I don't know why you mix in Hispanic communities here, I don't know many Hispanic people who speak that way, unless you're talking about a bunch of adolescent wanna be cholos who call each other the n word, but that has nothing to do with being Hispanic, that's completely adopted from shitty American hip hop culture.
