This statement does not make sense to me. Democrats and other leftists, Facists, Communists, and socialists clearly have disordered minds. They thus have NO capacity for reason to start with. They are dreamers who want to force the rest of us to conform to their warped and twisted view of the world. They are succeeding.
Bill Clinton, and to a lesser extent Jimmy Carter, were beneficiaries of the hero-worship.
O'bama is the perfect storm, though. In addition to the plain old vanilla hero worship, he's got the politically-correct crowd on his side. Being black, and maybe Muslim, just adds to the attraction.
