Commissioner Adelstein went the furthest, saying "this national transition has been mismanaged and plagued by the lack of a coherent and coordinated strategy. More time was desperately needed to correct the mistakes that many, including leaders in Congress, the Government Accountability Office, and every current member of the FCC, have long raised."
While it's certainly true that Kevin Martin's laissez-faire approach to the transition was criticized by the GAO, the other commissioners haven't exactly been outspoken opponents, at least not publically.
Sure Commissioner McDowell sent a letter to Martin complaining about the situation. But in typical Washington DC fashion he waited until a week before the then-Chairman was scheduled to step down - just a month before the February 17 deadline originally set for the transition. If he, or anyone else who was in office at the time, would like to point fingers they would be well served by stepping in front of a mirror first.
