Manning has given us a timely warning as both the NDP and Conservatives seek new Party leadership. Populous movements have never been easier thanks to the internet/mass media alliance. Past demagogues had to depend mainly on their leather-lunged voice supplemented by megaphones and after the 1920's,microphones. Audiences were naive about the wiles of propaganda. Today's audiences might be less naive, but based on the results of the US election and Brexit, just as easily seduced.
