A friend passes along how liberal authors see public radio as the most natural part of their product pitch. On his blog, Chris Mooney noted he would be plugging his book “The Republican War Against Science” on Tuesday with host Ben Merens on the “Ideas Network” at Wisconsin Public Radio. “I’ll be talking about the book, which they’re using as a premium in their pledge drive.” If you listen to the first minute of the show, Merens promised a copy of the book with any $150 pledge.
