I sense a bus being driven over Joe’s back in the not too distant future.

NANCY O’DELL, ENTERTAINMENT TONIGHT: “Sarah Palin coming out and saying that you should replace Biden with Hillary after his chains comment?”

PRESIDENT OBAMA: “Actually, I hadn’t heard it.”

O’DELL: “This is the first time you heard of it? What do you think of it?”

OBAMA: “You know, look, we don’t spend a lot of time worrying about the chatter. You know, the country’s not as divided or obsessed with gaffes or some stray remark as Washington is.”

O’DELL: “When you first heard that Biden had made the comment, that they were going to put y’all back in chains, when you heard it was phrased that way, what was your reaction?”

OBAMA: “What Joe Biden was talking about, again, is an example of a substantive argument, a substantive issue that the American people should be concerned about, and his phrasing is a distraction from what is at stake.”
