The State of Maine has set up an official web site where voters for Donald J. Trump and Michael R. Pence may check on the status of their absentee ballot requests. If a Donald Trump voter has not yet requested an absentee ballot but wishes to vote in that manner, the State of Maine also has an online absentee ballot request form.
If the ballot tracking system is unable to find information about a ballot request, it offers no solution except to contact the municipal clerk in your town of registration.
If the voter is a uniformed service member serving overseas, it is especially important to check the status of the ballot. It has been reported that, in some Democrat controlled states, the absentee ballots of military voters have been discarded or misplaced. This disenfranchisement of military voters has been an issue since before the civil war when many Democrat controlled states refused to allow absentee voting for soldiers.
