Beat me to it. Apparently, the author is a product of the public education system...now she could have had the lobotomy a year after her brother became president, but even with that, the numbers don't add up.
The author also has no evidence to attribute to this claim. As my father is fond of saying..."In God we Trust..Everyone else needs data."
That's the sort of "newspeak" sentence that makes you give up on the article. And once that is done, Rosemary sinks further into obscurity-- a backhanded favor to the Kennedys.
