Did you just discover narratives? I can't really telling because you said "GOP is reflecting" which isn't really true and not what I said. But maybe that's what you meant?

Biden has to respond to the narrative. The narrative is there because of the GOP. They're setting it.

Democrats do the same. But they're usually not as good at it since they are expected to be truthful.

(eg GOP lies about immigrants being evil. DNC gives warnings about abortion that come true.)
