The Overton Window by Glenn Beck

Glenn Beck's latest novel shows how a country can be changed by manipulating ideas so that previously radical and extreme ideas are seen by the general public to be normal and acceptable. In particular Beck shows how often described "progressive" ideas, previously considered fringe, became during the 20th century accepted by the mainstream. A must read to understand how a Marxist extremist such as Barack Hussein Obama managed to be elected president of the United States.
