A longtime Senator from Arizona and Vietnam war veteran, McCain's political career has all been a cover-up for his criminal activity as part of a ring of elite thieves with Barack Obama and David Quincy. He and Obama orchestrated every move of the 2008 election to get Obama in the White House so they could pull off the ultimate theft - the long-believed 'ungettable' Hope Diamond. He was presumed dead in the same explosion that killed Sarah Palin and David Quincy on Election Day 2008, but is alive under an unknown alias in the Caribbean.
