The discussions are mostly meaningless during the general election cause Republicans have been pursuing the Southern Strategy for 54 years. That strategy hinges on the fact that the racist White vote is far larger than the Black vote. As Nixon's own political strategist said:
Republicans are never going to cater to Black folk seriously because their racist white base is far larger than any potential black vote. The most they'll do is pander occasionally to try to skim a few easy votes off the top. But they're bound only to make the slightest concessions, just enough that their racist white base knows they still have their backs. The Repulicans' primary engagement with Black voters is working to depress turnout.
So the leverage is with the Dems. But the Dems know that Black folk will never vote for Republicans who consider them avowed enemies. So there's only two ways to affect Dem policy.
#1. Voting for the most pro-Black candidates in the primaries. The Black vote is large enough that it can shift the Dem primary enormously. IF Black vote voted in the primaries, and aimed for the candidate with the most trustworthy pro-Black policies, it would make a huge difference in huge the nominee is.
#2. Punishing the Democratic Party with poor turnout when they don't put up a pro-Black candidate. Even though there's no threat to go Republican, the community can still use turnout as a threat.
The big problem this year was that both #1 and #2 got fukked up cause Black folk went for Biden in the primaries.
