WASHINGTON — The Supreme Court on Tuesday cleared the way for early voting in Ohio the weekend before Election Day. The justices, in a one-sentence order without noted dissents, let stand an appeals court ruling that had blocked the efforts of officials in Ohio to restrict early voting there. The Supreme Court’s action was a victory for the Obama campaign, which had sued to overturn the restrictions.

Ohio had planned to eliminate early voting for several days just before the election next month, but it made an exception for members of the military. This month, the United States Court of Appeals for the Sixth Circuit, in Cincinnati, ruled that early voting must be offered to all voters if it is offered to the military.

The Obama campaign had argued that poor, elderly and minority voters often vote the weekend before Election Day. It said more than 100,000 people in Ohio voted in the same period in 2008.

Ohio officials justified the restrictions by saying that local administrators were too busy preparing for Election Day to accommodate early voting the weekend before, an assertion some local administrators disputed. The state officials added that an exception was warranted for military personnel because they may be deployed on short notice.
