You got it. The laughs come from elements of truth and that requires recognition. I have no memory of hearing Bannon speak. We hear Spicer all of the time. Melissa McCarthy picks up parts of the rhythm and content of a Spicer briefing. What could Rosie and the writers do with Bannon other than make stuff up that nobody understands?
Have "him" spout racist comments.
My exact thoughts: no one knows Bannon, his mannerisms or his voice. What’s the point? It’s like imitating the voice of a silent film star.
