A disturbing report by Max Blumenthal. Money quote:
When President Obama took office, Arizona's anti-immigrant right fused with extreme elements of the religious right under the Tea Party banner. In August 2009, a young man called Chris Broughton openly carried an AR-15 assault rifle and a handgun to an Obama rally in Phoenix. The night before, Broughton had attended a sermon called "Why I hate Barack Obama" given by the Rev Steven Anderson, a local Tea Party activist. Anderson declared that that night he was going to "pray for Barack Obama to die and go to hell".
