Gregory Palast is almost certainly the greatest investigative journalist you’ve never heard of. An award-winning reporter in Britain, where he writes for The Guardian and The Sunday Observer, as well as hosts the BBC’s 60 Minutes-esque Newsnight, Palast abandoned his native America when the mainstream press declined to publish his groundbreaking, hard-hitting exposes, known for stripping bare abuses of power. Case in point: his recent series on how Jeb Bush and Katherine Harris conspired to illegally purge the Florida voting rolls of thousands of former felons whose voting rights had been restored by other states, the vast majority of whom were (not coincidentally) Democrats. In the few venues that have bothered to report it in the United States, it’s caused scarcely a ripple. Palast will be in Cleveland on Tuesday to debunk reigning myths about the much-touted phenomenon known as globalization.
