EXACTLY what tapes is Mark Penn referring to?

Jen Rubin passes on a great little tibit from the document dump from the Atlantic. You want to read this one which contains Mark Penn’s analysis just prior to the Iowa Caucus.

On page 8, in the scenario that Hillary Clinton comes in second behind Barack Obama, Penn recommends:

If it is a two-way race with Obama, on Friday we do a media interviews (sic) and basically say that he is unvetted, discuss his ever-changing positions. Release the tapes. Create immediate pressure that deprives him of oxygen

What tapes? If it is the Wright tapes, why did it take so long? If it is something else…, what tapes?
