About 10 years ago I was approached by Oprah's producers to be on her show. I showed no interest but they were very persistent. They called me every day and tried to get me to change my mind, but I told them "No" every time. They eventually called my boss (!) and tried to get him to convince me to be on her show. Luckily, he was aware that they were harassing me and took my side and basically told them to leave me alone.
I respect Oprah for what she has accomplished but I detest how her producers deal with "recruiting" the people who go on her show to tell their stories. All they care about is being sensationalistic so they can hook their audience. They don't give a flying fuck about the people who go on the show or how going on the show affects them afterwards.
So, when I question whether Oprah's people are rigging the vote? Well, my mind is made up. It's pretty obvious to me.
But don't be surprised if Oprah "reaches out" to Zach and has him on her show but doesn't choose him to have his own show.
