Horowitz is president of the David Horowitz Freedom Center. A former New Left Marxist in the 1960s, Horowitz later renounced his radical beliefs and became a patriotic conservative American. Horowitz is also the New York Times bestselling author of The Shadow Party: How George Soros, Hillary Clinton, and Sixties Radicals Seized Control of the Democratic Party.
Here is Horowitz's endorsement:
Matthew Vadum has created a well-researched, irresistibly written book that every American should read. The criminal enterprise called 'ACORN' is the largest, most elusive, and most dangerous radical organization in America. If you are wondering about the operations and influence of a vast left-wing conspiracy, this is it, with tentacles that reach right into the heart of the Obama White House.ACORN is restructuring in time to help re-elect President Obama in 2012. Obama used to work for ACORN and represented the group in court as its lawyer.
