Kevin Drum is a rabid rabid rabid Bush hater, and even HE had doubts about Burkett's credibility.
November 2000 Burkett says he wasn't trying to point a fingure and makes no mention of having any docs...

,,,,,Question: Did you allege that the governor’s staff “doctored” the records?
Burkette: No, instead I stated that the way this had been handled by the Bush staff, including knowledgeable military officials at the Texas National Guard, that it left the implication that the Bush staff had first incompetently provided an incomplete military file for the Governor which was consistent with his autobiography. I further observed that they probably did not anticipate that the file would be scrutinized to the level that it was. Whenever someone determined holes in service “big enough to drive a Mack truck through,” additional information—all of which was unofficial and some in pencil notations—were then submitted to the press to answer questions. I further observed the this “trust me, I’m the Governor” approach had worked throughout Texas for George W. Bush within his tenure and the media had given the Governor a free pass, without the same scrutiny as the vice president [was given], until the eleventh hour revelation of the DUI. But this still left the basic question: Why didn’t Governor Bush simply release his military pay files and retirement points accounting records, which are the only official records that will show that he satisfactorily and honorably completed his service commitment?,,,,,,,
