Marked by accusations and backstabbing, it's the story of how a small but intense movement called"birthers" rose from a handful of people prone to seeing conspiracies, aided by the Internet, magnified without evidence by eager radio and cable TV hosts, and eventually ratified by a small group of Republican politicians working to keep the story alive on the floors of Congress and the campaign trails of the Midwest.

It's a powerful story about what experts call political paranoia over a new face in a time of anxiety and rapid change - the sort of viral message that can take hold among a sliver of the populace that's ready to believe that their new president is a fraud, and just as ready to angrily dismiss anyone who disagrees with them as part of the conspiracy.
