A book titled “Reasons to Vote for Democrats: A Comprehensive Guide,” written by a Republican author and full of only blank pages, has shot to the top of the Amazon bestseller list. The guide, which features 266 empty pages and retails for $8, has only a table of contents, chapters, and a bibliography, but no actual words.

The book was written as a joke, but sales have skyrocketed. Author Michael J. Knowles told Fox News that when he took a look at the Democrats’ “record and reasons to vote for them,” he thought “it was probably best to just leave all the pages blank.”

The description on Amazon doesn’t explain the joke, which means that some of those sales could have been sincere. The only description on Amazon reads:

The most exhaustively researched and coherently argued Democrat Party apologia to date, “Reasons To Vote For Democrats: A Comprehensive Guide” is a political treatise sure to stand the test of time. A must-have addition to any political observer’s coffee table. “Thorough” –Ben Shapiro, nationally syndicated columnist and New York Times bestselling author
