Number of Hate Groups in the US Has Risen 755 Percent Since the Election of Obama, New Report Says

The election of President Obama triggered an explosion in the number of hate groups in the US, according to a new report from the Southern Poverty Law Center. The rise in numbers is due to changing racial demographics, a bad economy, and a divisive political atmosphere.  

Mark Potok, who wrote the report, is the Director of the Southern Poverty Law Center's Intelligence Project.
