In TN an absentee ballot is one that is acquired by the voter personally presenting him/herself to the election commission and showing a picture ID and filling in a form and signing ...
Then the ballot is sent to him/her and it is to be cast and signed and sent back to be received by the close of the polls (8pm) on Nov 3.
The signature on the ballot must match up with the signature on the request form...
other than that what do you have ???
