Making sure such voters can cast ballots in federal elections is the mission of the Federal Voting Assistance Program (FVAP), a Defense Department office that offers assistance not just to military personnel, but to any U.S. citizen who needs help casting a ballot from overseas. It offers resources, including a wizard on its website that takes a voter through the entire process of registering to vote and casting a ballot in the appropriate jurisdiction. But Robert Carey, FVAP’s director, said his office’s assistance role to state and local governments is just as important. … Carey said 2009 was a watershed year in terms of election law changes designed to improve voter participation among servicemembers and overseas voters. Among other things, the Military and Overseas Voter Empowerment (MOVE) Act requires state and local elections officials to mail absentee ballots to servicemembers at least 45 days prior to an election in order to ensure a ballot can make its way to a remote location — and back to elections officials — in time to be counted.
