Who Do You Think Possesses 'Moral Authority' in America?

The question, "Who Do You Think Possesses 'Moral Authority' in America?" is being considered on a popular blog at The Atlantic magazine edited by Andrew Sullivan, with a hat tip to Mark Kleiman.

The excerpt below gives an idea of what they are taking "moral authority" to mean.

“Who in contemporary America has moral authority?”... I took this to mean both “moral authority you are prepared to accept” and “enough public standing to be an actual force....”

who

...has the intellectual force, the moral clarity, and the nerve...

but does not lack the necessary...

... notoriety, nor the impulse to seek it out... I could come up with only one name: Barack Obama. Could it really be true that there is no other political leader, journalist, academic, religious figure, business leader, trade unionist currently active with the stature to summon people to action based on moral authority as opposed to self-interest?

It seems to me that the field wasn’t always so empty.

And then he lists:
Martin Luther King Jr.
Adlai Stevenson
Edward R. Murrow
Walter Cronkite


So, who do you think has moral authority today?
