In case there was any remaining confusion with regard to the precise political intentions of the US Supreme Court’s activist majority, things were clarified Monday. The same majority that has made it easier for corporations to buy elections (with the Citizens United v. FEC decision) and for billionaires to become the dominant players in elections across the country (with the McCutcheon v. FEC decision) decided to make it harder for people in Ohio to vote.

Yes, this Court has messed with voting rights before, frequently and in damaging ways. It has barely been a year since the majority struck down key elements of the Voting Rights Act.

But Monday’s decision by the majority was especially blatant—and immediate. One day before early voting was set to begin in Ohio on Tuesday, the Supreme Court delayed the start of the process with a decision that will reduce the early voting period from thirty-five days to twenty-eight days.

Assaults on early voting are particularly troublesome, as the changes limit the time available for working people to cast ballots and increase the likelihood of long lines on Election Day. And changes of this kind are doubly troublesome when they come in close proximity to high-stakes elections, as they create confusion about when and how to vote.

American Civil Liberties Union of Ohio Executive Director Freda Levenson decried the ruling, calling it “a real loss for Ohio voters, especially those who must use evenings, weekends and same-day voter registration to cast their ballot.”

The ACLU fought the legal battle for extended early voting on behalf of the National Association of Colored People and the League of Women Voters, among others.

“To make (the Supreme Court ruling) even worse,” Levenson told the Cleveland Plain Dealer, “this last-minute decision will cause tremendous confusion among Ohioans about when and how they can vote.”

Ohio Republicans had no complaints. They have made no secret of their disdain for extended early voting, which has been allowed for a number of years and which has become a standard part of the political process in urban areas where voters seek to avoid the long lines that have plagued Ohio on past Election Days.

Ohio Secretary of State Jon Husted, a top Republican, has taken the lead in efforts to restrict voting. In June, he established a restricted voting schedule. Husted’s scheme was upset by lower-court rulings. In particular, the courts sought to preserve early voting in the evening and on Sundays, which is especially important for working people.

Fully aware of that reality, the Supreme Court scrambled to issue a 5-4 decision that “temporarily” allows the limits on early voting to be restored. Chief Justice John Roberts and Justices Samuel Alito, Clarence Thomas, Antonin Scalia and Anthony M. Kennedy voted to allow Husted to limit voting, while Justices Ruth Bader Ginsberg, Stephen Breyer, Sonia Sotomayor and Elena Kagan opposed the ruling.

Monday’s ruling was not a final decision; the Court could revisit the matter. But that won’t happen in time to restore full early voting before his year’s November 4 election.

The Court is sending a single of at least tacit approval of controversial moves by officials in other states—such as Wisconsin and North Carolina– to curtail early voting and access to the polls. Legal wrangling also continues over the implementation of restrictive Voter ID rules in those states and others—with special concern regarding Wisconsin, where a September federal appeals court ruling has officials scrambling to implement a Voter ID law that had been blocked by a lower-court judge.

Expressing disappointment that a narrow majority on the Supreme Court has permitted “changes that could make it harder for tens of thousands of Ohioans to vote,” Wendy Weiser, the director of the Democracy Program at the Brennan Center for Justice at the NYU School of Law, said, “Courts should serve as a bulwark against rollbacks to voting rights and prevent politicians from disenfranchising voters for political reasons.”

Weiser is right.

Unfortunately, the High Court is focused on expanding the influence of billionaires, not voters.
