I think it would work. Candidates always need money. You either back candidates who say they are for reparations and push it for it, like Marcel Dixon or you rent/lease votes like everyone else does.
Big Pharma, the Defense industry, and other areas give money to both Dems and Republicans. Typically they try to buy off the representatives or senators that serve or chair a committee that oversees their interests.
We (Blacks) can do they same. It works for everyone else with a PAC. As an example, whatever committee has HR40 you simply have your lobbyist hit them all up and say how much you need to vote our way or change the bill? Simple as that. You don't give a f*ck if they believe it or not, you are buying their votes.
