I think the Republicans are doing a big brain centrism by admitting systemic racism is real, but saying it’s all the democrats’ fault, while also saying the police are necessary and good, and bringing out black conservatives as speakers to back them up.

I think it's much simpler than that. They're just throwing every possible argument out there, even contradictory ones, because Republicans will lap up whatever they say and one argument might click with someone who's thinking about not voting for Biden.
