I think Kerry has someone at the records repository that is working on cleaning up the record that is there. It could get lost which is plausible and likely considering the furor being brought out for him to sign the SF 180. There was a fire in 1973 at the St. Louis Records Facility but Kerry's record would not have been there, especially when his DD214 was beginning to show a DC or a General Discharge.
The US Senate HAS his records, all of them!
He could not get a top secret clearance without his records.
The US Senate is behind the coverup!
