I only know her name because I work for a book distributor.
Her titles aren't selling like they used to, either, if that's any consolation. They still hit the major bestseller lists, but those are based on the books ordered, not sold. They don't take into account the numbers of copies that are later returned by stores and distributors, and in the case of her titles those returns are generally very high. That's often true of the more extreme writers, no matter their political affiliations, but more so for her, I think, at least with her more recent titles.
