Rush Limbaugh’s first book in twenty years, due out in October, is a children’s tome called Rush Revere and the Brave Pilgrims: Time-Travel Adventures With Exceptional Americans. Subtle! But this is not just run-of-the-mill vanity fiction. There’s an extra layer of promotion, as the main character, Rush Revere, is also the face of Limbaugh’s line of conservative iced beverages, Two If by Tea. Bedtime reading may never be the same.
