Oprah has, for decades, pedaled new age psycho-babble, bogus medicine and all manner of snake oil on her shows. This is a fact.
Even with this unfortunate history acknowledged, no one who is seriously discussing this is suggesting that Oprah’s utter lack of qualification for the presidency of the US derives from some ontological or cognitive deficit. Oprah’s utter lack of qualification to be president derives from the objective fact that she has no relevant preparatory experience.
The notion that Oprah should run for president is as absurd as the notion that Obama should start performing heart surgery. As absurd the notion that Tom Brady should be governor of Massachusetts. As ridiculous as the suggestion that Mitch McConnel should become a deep sea rescue diver.
This much stated, I would very much like to see the democrats nominate a qualified woman candidate for POTUS.
Elizabeth Warren comes to mind. Oprah does not.
