T-ball was invented in 1961. At least that’s one claim.
If the narrative about Barry being the created-from-conception onward chosen messiah of red-diaper Marxism and a killing rebuke to the mighty white US (and the colonial powers England and The Netherlands) by the Indonesians, Black Muslims and the Mau-Mau, is golden, then his wife and her family are also a big factor. He was picked, she also had to have been picked, as was Valerie Jarrett as the minder.
There was a discussion about T-ball in the past, and the conclusion appeared to be that T-ball was not in Hawaii during the time frame claimed by Abercommie.
