22 December 2004: Editor's note: Sources now tell me that not only is Bob Walker's name not under consideration for NASA Administrator, but moreover, that he has made it clear to those who ask that he is not interested in the job.
19 December 2004: Editor's note: After a week of speculation and rumor mongering the following evolution of the purported names being considered for NASA Adminstrator has developed:
Names still in play: Steidle and Walker, and to a lesser extent, Kadish and Worden (despite Brownback's endorsement).
Names no longer in play: Bolden, Sega, Crippen, Culbertson, Elachi
