Even with all the uproar over Clarke, the 9-11 Commission still seems like a whitewash to me. Do you think BushCo will play the Clarence Thomas card? Will Condi take the 5th at any point? My feeling is she'll get a pass. It'll be "he said - she said" and that'll be where it stays til the next media eruption.
But what questions could be asked that'd really nail Rice to the wall? Will Rice be the (yum!) sacrificial lamb?
