Currently, there are thirty-two (32) states that allow absentee voting. In these states, the voter takes action to request an absentee ballot. They can call, go online or write a letter to request the ballot. Some states require an excuse, and others do not.
The voter has to submit her or her name and address and receives two envelopes. One is a sealed envelope where the voter places his or her ballot. This enveope is signed by the voter. Then there is a security envelope. Local election authorities verify the name of the voter to ensure that he or she is registtered with the election authority. They then remove thee sealed ballot from the outside envelope containing the voter's signature, so it is confidential.
