The Supreme Court said Tuesday that early voting can proceed in Ohio — a major win for President Obama.

In a one-sentence order with no explanation, the court rejected Ohio Republicans’ efforts to block early voting three days before Election Day. The court left in place a lower-court ruling that said early voting had to be available to all Ohioans — not just military personnel.

The rejection is a victory for Obama. Democrats initiated the legal battle over Ohio’s early voting policy, after state officials decided to eliminate three days of early voting that had been offered in 2008. Minorities, who traditionally favor Democrats, are seen as most likely to take advantage of early voting.
