Marianne Williamson is the only presidential candidate that has made it to a national TeeVee debate stage that I ever had lunch with.
That was back about 1990, when she was just getting started on the lecture circuit, talking about A Course in Miracles. Long before “A Return to Love,” Oprah, or the 2020 Democratic Party primaries.
At the time I met her, I was in Los Angeles training for my brief career (1990-1991) as a Series 7 securities peddler. I heard Marianne at one of her lectures at a church in West Los Angeles, talking about how she was 
financially insecure, so I approached her after the lecture and we arranged a lunch meeting. Nothing came of it beyond that, other than the recollection that that was one of the most intense lunch meetings I ever had.
If nothing else, she and I are both Truman Babies (she 1952, me 1950).
