Religion in Politics
"Hillary-hating is a religion, and belief in religious truth does not need a logical rationale." Posting on a NYTimes blog.
The exact same thing can be said of support for Obama. It is a personality cult, like worship of Mohammed or of Jesus Christ. Oprah stated her views very well: "I have seen my truth," in speaking of her support for Obama. Another way of putting is: "Don't bother me with the facts. My mind is made up."
To sum up, Obama benefits from three forces: Hillary-hate, religious passion and Black racism.
