There is more cause for concern after the ballots arrive at the Pentagon. E-mail voters will be required to sign a release acknowledging that their votes may not be kept secret. When the people handling ballots know who they are cast for, it is not hard to imagine that ballots for disfavored candidates could accidentally be "lost." And because the e-mailed ballots arrive as computer documents, it is possible to cut off the voter's digitized signature, attach it to a ballot supporting another candidate, and send that ballot on to the state to be counted.
