Ohio wins ruling in purging voters from registration

The United States Supreme Court is allowing Ohio to clean up its voting rolls by targeting people who haven't cast ballots in a while.

The justices are rejecting, by a 5-4 vote, arguments that the practice violates a federal law intended to increase the ranks of registered voters. Justice Samuel Alito says that Ohio is complying with the 1993 National Voter Registration Act. The Ohio law allows the state to send address confirmation notices to voters who have not engaged in voter activity for two years. If a voter responds to the notice, the information is updated. If there is no response and if the voter doesn't update their information over the next four years, then their registration is dropped. 

Only a handful of states use a process similar to Ohio's, but others could because of the Supreme Court ruling.
