The (Ugly) Real Reason White Conservatives Like Herschel Walker:
OK, nobody is saying this, so I'll say it: for white conservatives, Herschel Walker's ignorance is a feature, not a bug. When Herschel Walker talks, he sounds exactly like every white racist's stereotype of a black man: an athletically gifted but academically useless ignoramus. His mangled syntax, country-fried pronunciations, and childish deceptions are exactly what white racists expect from a black man. He's like a real-life version of Buckwheat from "The Little Rascals".
The reason white racists think they don't hate black people is because they actually like black people ... as long as those black people are conforming to white racists' low expectations of them. That's where the perjorative "uppity" came from. They hate when black people exceed those low expectations, the way Obama did. Herschel Walker acts exactly the way white racists expect a black man to act. This makes them happy.
If Herschel Walker wins, Republicans win twice: not only do they get another seat, but they get to use it to promote their negative stereotype of black men, by putting a useful idiot into that seat who doesn't even realize that they're making fun of him behind his back.
