I don't agree with his take that people shouldn't ask. That comes with caveats because he was right about two things:
-If she promises anything specifically to black people, it's weaponized. That is fine if her calculus says it is the right move, but with us being the portion of the country we are, it has to be something folks consider benign otherwise it absolutely stops her in her tracks.
-He is right about "If we don't vote, why should they care?" due to analytics. Its the same reason politicians, correctly or incorrectly, are choosy about their audiences when they tour. Some places and people just aren't going to vote for them. If we collectively hold our votes, especially for single issues, we run into issues of not being a viable target for whatever policies come, especially all-encompassing legislation that helps everyone. Not voting is a bad strategy.
That said, people literally have the right to take politicians to task and they do change course due to public opinion often. The problem is people want the President to do what generally is going to come from Congress. If you want a black-only initiative, we need the executive and legislative branches to sign and craft bills respectively. Putting all of our hopes in one candidate with no help is how we end up disappointed. The people absolutely should keep their foots on Kamalas neck about black folks needs.
