Is that a joke?
Of course I did. In fact, I knew who Frank Davis was a while ago, what Obama wrote about him in his own biography, and what others have written about their mentor/student relationship when Obama was young.
Bet you didn't know who Frank Davis was before you saw that link. That's perfectly okay. But I bet you still didn't know who he was when you decided to post that snarky piece, which is less okay. And I bet you still don't know who he is even now.
