Disinformation - the deliberate spreading of lies disguised as truth, whether from opportunists on the far right, misinformed media influencers, or others-is fragmenting America more than ever before, pushing the nation toward extreme views, civil unrest, and violence. In this bestselling book, now with a new foreword by the author, Barbara McQuade identifies how disinformation is seeping into all facets of our society, causing havoc in our voting systems, schools, hospitals, workplaces, and the Capitol. McQuade, an MSNBC legal analyst and former federal prosecutor confronts the ways disinformation is being weaponized to polarize voters, degrade our legal structures, and leverage the political influence of manipulators and authoritarians. Now newly updated, Attack from Within shows us how to fight back against misinformed, extremist thinking and work toward preserving America's hard-won democracy.
