Some states will provide a "Special Write-in Absentee Ballot" upon your special request. This is a blank write-in ballot sent well in advance of the General Election, if special conditions apply.
If you believe that you will be unable to vote and return a regular absentee ballot (due to military service, living in a remote area, or other contingencies) by normal mail delivery within the period provided for regular absentee ballots, then you can add a written request (on the Addendum page that will print when you use the voter registration service) to request this special advance ballot.
Keep in mind, this special ballot is blank and is sent far in advance of the election -- up to 90 days ahead in some states. It is for voters who are in remote or hostile areas, or who cannot count on normal mail delivery times.
To contact your local election official to confirm if you can request a Special Write-in Ballot Option, please look them up in the Election Official Directory on this website.
