In light of the fact that the 2016 MM is coming up around the same time that a very crucial election is taking place in the USA, it is very important for those who will be on the 2016 MM to be aware of voting alternatives available to them, especially those who would already be outside of the USA by the November 8, 2016 presidential election day!
Generally there are two options, if you have to vote before the election day:
1. You can either go to a satellite voting center/local voting office where you can cast your vote
2. You can request a mail-in absentee ballot, cast your vote, and return to the local office
Since this may vary slightly from state to state, below are links to provide specifics by state:
