I voted absentee because I was concerned about fraud of electronic voting. It may be that many democrats voted absentee for the same reason. Therefore Absentee ballots would lean democratic.

The absentee voter ballots may not therefore represent a true cross section of the electorate.

This does not mean that fraud did not happen but it might explain the difference between absentee and electronic results.
