Connect the dots...
Obama hung with Davis in Hawaii..
He then went to Occidental College in LA but moved on to Columbia where he most almost certainly met Bill Ayers, who had the same “smash monogamy” agenda of homosexuality and group sex as Davis which was documented in various media both film and written.
Obama may even have lived with Ayers and his wife in New York, they were at college within a quarter mile of each other and both lived off campus...
Then subsequently we get the accusations of Larry Sinclair
Not likely, there's a FR post that gives an Upper East Side address for B. Obama. B. Ayers and B. Dorhn have address on the Lower West side. Check #34 and #52
