Other than the email from the University of Hawaii stating the she was enrolled there for the Fall '60 semester, and then latter of course starting in '63 until she got her BS, MS, and PhD. (with breaks in between).
A scan of an e-mail? not very convincing...sorry, I want to see more than that. All the letters of recommendation written for Obama Senior in that period NEVER mention his ‘wife and child’.
Simple explanation.
He wasn’t married to Stanley Ann because she wasn’t on the island, and he didn’t have a child with Stanley Ann. That’s my take and I’m stickin’ to it.
