You have to make a calculation when you go on shows hosted by liberals like Jon Stewart. They are not going to allow you to actually discuss your book. Their audiences are prepped to laugh at whatever the host says and react negatively to whatever the author says. And when their writers aren’t striking, the host is armed with a bunch of jokes to mock the author. So, you have to weigh that against a couple of mentions of the book, and whether the entire enterprise is worth it.
