Saturday Night Live would have to invent him. He responds to Josh Marshall’s response to his ranting and calls out Marshall again.
I find it hard to determine if the whole act is just a way to get more donors as Josh Marshall has suggested previously, or if Horowitz is so incredibly dim-witted he can’t actually tell that his whole victimhood schtick is the ultimate in PC whining. Then again, either way it is pretty damn funny–well except some people actually believe him.
