She's not really crazy. Rather, it's all part of "the game" the Dems play.

She knows the composition of her voting base and knows that she needs to keep the blacks focused on their "plight", always "wanting" and looking to her/the Dems to "save them", and that if she doesn't patronize the blacks, reinforce their victimhood and promise them special recognition, special treatment, and gimmes (even if she knows those promises are unconstitutional/⁵illegal and/or there's no way she can deliver on them), she won't get the blacks' actual support/vote (or the credible illusion of their support/vote in a rigged election).
