The Obama campaign has challenged an Ohio law that extends the early voting period for members of the military, but not for civilians. The focus is on the three days right before Election Day. Under the new law, service members stationed in Ohio can continue to vote in person on Saturday, Sunday, and Monday before the election, but civilians can cast early votes only through Friday. When the Obama campaign asked a federal court to open the full early voting period to all voters, Mitt Romney accused the President of trying to undermine military voting rights. Republicans said the lawsuit questioned whether it was constitutional to ever make accommodations for military voters. This characterization is inaccurate, and silly. There is a long history of accommodation for military and overseas citizens to vote by absentee ballot (for example, the federal Uniformed and Overseas Citizens Absentee Voting Act), and this is a settled understanding. The Ohio law is the first, as far as I know, to grant extra voting privileges to service members voting in person, not by absentee ballot. The Obama campaign is not arguing that service members are never entitled to accommodation based on the unpredictable circumstances of their assignments, but only that it is arbitrary to hold “military-only” voting days when all voters are physically present and able to vote in person. If the election offices are going to be open, we should let everyone in the door.
