Greenberg is full of it. I saw the clip and there was a definite pause, as in wink-wink-nudge-nudge. Not only that, there were boos from a few in the crowd and Obama said, "That's all right, that's all right" as if to say dissent is OK. If he was as smart as Greenberg implies, Obama would have caught himself and say something along the line of "Hey, don't get upset, I didn't mean it that way."
As with the hand-to-cheek aka "the finger" to Hillary, he knew EXACTLY what he was doing.
“As with the hand-to-cheek aka “the finger” to Hillary, he knew EXACTLY what he was doing.”
That’s my reading also. And let’s not forget the “3 AM” e-mail saying Biden was his choice. This behavior is petty by any standard, and very petty in someone who would be President.
Greenberg missed the boat on this one.
