An absentee ballot is a special ballot which allows voters to cast their vote without going to the polls. An absentee ballot may be used for a variety of reasons. One of the more common is that a voter wishes to vote in their home district, but is unable to for one of a variety of reasons. Two examples of such reasons might be that they are away at university, or that they are in the military. Others may choose an absentee ballot because it is a paper ballot and they are nervous about voting electronically at a polling place.
