Half a hoax, the Palin ignorance part is true. The hoax is limited to WHO leaked it.
That Palin is almost completely ignorant of affairs past what an Alaskan pipeline can do for her and her family is not at question here. Your citation verifies that, and Fox "News" Channel says it's true.
"The pranksters behind Eisenstadt acknowledge that he was not, through them, the anonymous source of the Palin leak. He just claimed falsely that he was the leaker--and they say they have no reason to cast doubt on the original story. For its part, Fox News Channel continues to stand behind its story."
