I say it’s Oprah. 100%.
Think about it. They never invite women, so for them to make this exception there must be something they need from her that they can’t get otherwise.
Madonna is famous but washed up; no one is following her anywhere. Jolie is ok but she is already a known quantity. Oprah, on the other hand, could be their best shot at the presidency in 2020. She processes self improvement and charity all the time, normie people have a positive image of her in general.
I read somewhere that the weekend at bohemian grove has more decisions made than a year in government. To me, this means that this ‘honor’ of attendance could only be for Oprah.
