Oprah???
Oprah certainly fits the profile I outlined.
And unlike some, she has some Native American ancestors. She certainly has name recognition as well as being wealthy (multi-billionaire). She has a rags to riches story and is currently head of several profit and non-profit organizations.
One can presume she leans left but does not appear to be as extreme as the current crop of candidates.
However she does have some skeletons in her closet while they may be open secrets to her fans I doubt most Americans know she tried heavy drugs (crack) when younger, and her sister may have died by a drug overdose.
If Oprah is going to be their savior she needs to begin getting her view of America out to Americans of all types, not just her core fans.
We will know she is in the running when we start seeing interviews and articles where she begins laying out her platform.
