Some notes about overseas voting from the Military Postal Service Agency:

As of today, the Agency has delivered 415,428 absentee ballots and returned 519,032 to local election officials. Officials said the reason for the difference is that some voters received ballots through other means, such as fax or email.

That number is total ballots, which includes family members and contractors who received their forms at overseas locations. Currently 270,000 military personnel are deployed for Operation Iraqi Freedom and Operation Enduring Freedom, and another 255,000 stationed at other overseas military bases

However, agency officials are quick to point out that those delivered ballots do not represent the total of all votes cast by overseas personnel. Twenty-six states allowed voted ballots to be submitted by fax and 11 allowed voted ballots by email, so some votes may not have been processed at all by the postal system.
