They like to pretend that nobody goes by their middle names. Though there isn't a single male in my family that goes by their first name. (I don't either, mine is just a single letter, it fits uncomfortably...). Because they believe that everybody must go by their first name they don't even read the middle name on the birth certificate (unless it is a democrat or a serial killer). They also want to insult, so they just act like a story like Haley's can't exist in this country unless they have a D next to their name.
Like I said before. Recognizing Diversity in the Republican Party would raise their IQ, that causes them pain, they do not like pain, so they refuse such recognition.
They wanted their D candidate to win because of genitalia, but when the same genitalia appears on the other side of the ticket it's not good enough to even be recognized for what it is. They come up with nonsense like she listed herself as white on some form, or that even though she goes by her middle name she "made that name up".
