Who should be on Obama's ticket?

So, we all know it wont be Senator Clinton, but whom should he choose? Does he go with a white male? Who would that be? Is Governor Richardson an option to bring the hispanic-Clinton vote back into the fold? Does he go with a woman to appease the outraged feminist camp? Am I crazy to think that Oprah would be a good choice? Imagine Vice President Winfrey on a Middle East goodwill trip!
