Walker Is

 Caroline Williams addresses this in another Atlantic essay:

Walker is a big, ball-carrying Black man, and these Republicans do not have an ounce of care for him. They are using him to advance their own Constitution-compromising agenda, the way conservative white people in this country have always used Black bodies when given half a chance.

Walker stands up at podiums, and I feel shame and sorrow and resentment. He is incoherent, bumbling, oily. He smiles with a swagger that does nothing to disguise his total ignorance of how blatantly he is being taken advantage of by a party that has never intended to serve people who look like him.

Walker's candidacy is a fundamental assault by the Republican Party on the dignity of Black Americans. How dare they so cynically use this buffoon as a shield for their obvious failings to meet the needs and expectations of Black voters? They hold him up and say, "See, our voters don't mind his race. We're not a racist party. We have Black people on our side too." Parading Walker at rallies like some kind of blue-ribbon livestock does not mean you have Black people on your side. What it means is that you are promoting a charlatan — a man morally and intellectually bereft enough, blithely egomaniacal enough, to sing and dance on the world stage against his own best interest. Is he in on the joke? Does he know they picked him to save money on boot black and burnt cork, this man who made his name by bringing the master glory on the master's field, who got comfortable eating from the master's table?...

From where I sit, the election looks like a kind of grotesque minstrelsy. The Republican Party is saying that it wants power more than decency. It's saying that race is a joke. We must all take note—it is willing to destroy a man to advance its cause. The party thinks he won't break. And if he does, well, he wasn't really one of them, anyway, was he?
