It's the kind of thinking that's got people seriously jabbing about Oprah as a Democratic candidate. We really want to put someone who was a talk show host and has evangelized quack science for the past 30 years in charge of the country, because she's all of a sudden brave enough to speak out against Harvey Weinstein (nevermind that she was his friend)?
The scary thing is, she'd probably beat Trump, that doesn't mean it would be good for this country. It really can't be that difficult to pick someone who is both more electable than Trump and also capable. If we can't do that, then let's fold up as a country and go home.
We don't have to default to someone like Oprah or Bezos. We can do better.
(For comparison, while plenty of people here have strong party affiliations over here in Holland, it's not a big deal and quite common even to be a 'floating' voter without too much allegiance to one party.)
