Following up on Stanley Fish's experiment; I went to the Strand Bookstore here in Manhattan to find a copy of Going Rogue. Yet not only did they not turn me away; they told me it was sold out! With six other people in line to buy it.
That's right. We read Sarah Palin here in the Blue States. And they read Obama in Red States. In some states, people even read Red State Blue State Rich State Poor State: Why Americans Vote the Way they Do (recommended, btw).
