Oliver Willis attacks the book via Twitter by disparaging the publisher, WND Books, instead of dealing with the book itself (which he hasn't read). Here is Willis's tweet:
Just wait till the folks at Media Matters see what's in the book! They're going to be burning the midnight oil futilely working to disprove all the damning evidence I've compiled.
Buy the book Subversion Inc.: How Obama's ACORN Red Shirts Are Still Terrorizing and Ripping Off American Taxpayers, which comes out tomorrow. Pre-order it now! If you'd like an autographed copy, order it directly from WND Books here.
