It’s all speculation Ron, but she has every right to explore the field and throw her hat in, if you think of all the jokers that run every 4 years there is no grounds to pre-emptively disqualify her or anyone, celebrity, politician or otherwise.
It is interesting to see Conservatives out in full force to tear her down, they must be really scared of the prospect of a liberal self-made minority billionaire bid.
What is more disheartening is that many progressive whites are also quite vocal about why we need a “policy wonk” or “technocrat” rather than Oprah. I’m willing to consider just about any credible contender, as long as they go the distance to oust the incumbent.
