According to Amazon’s data, conservative/libertarian books outsell liberal books by a 57-43 margin. In Pennsylvania the margin is 52-48. I don’t know exactly what to make of that, but it’s interesting. With the intelligentsia being so liberal, I would have expected it the other way.
One thing is for certain: publishers that drop writers who come out as conservative or libertarian (like Sarah Hoyt) are making a big mistake.
