I don't think bruhs will flock to the Republicans, we just won't vote
I don't think flock but a gradual uptick will probably occur. I mean its no where else the dems can go. They got a black male president. Unless its really ground brealing policy or really working for the black male vote their will be more gradual slip.
Maybe outside of ground breaking policy if they got a "black male american" (ados no brown paper bag test) as a presidential nomination into the white house maybe that would energize the black male base.
But other than policy and a "that type" of candidate I don't see how they slow down the gradual bleeding.
