A U.S. Supreme Court ruling has cleared the way for states to take a tougher approach to maintaining their voter rolls, but will they?

Ohio plans to resume its process for removing inactive voters after it was affirmed in Monday's 5-4 ruling. It takes a particularly aggressive approach that appears to be an outlier among states.

Few appear eager to follow. "Our law has been on the books. It hasn't changed, and it isn't changing," said Oklahoma Election Board spokesman Bryan Dean.

At issue is when a state begins the process to notify and ultimately remove people from the rolls after a period of non-voting. In most states with similar laws, that process begins after voters miss two or more federal elections.

In Ohio, under the current Republican secretary of state, it starts if voters sit out just one election. They are removed from the rolls if they miss three federal elections over six years and fail to return an address-confirmation card.

Oklahoma is among the states that send confirmation notices to voters who have failed to cast ballots in two elections. As in most other states, voters who fail to respond are made inactive or taken off the rolls altogether if they don't cast a ballot in subsequent elections.

Opponents of the laws say their intent is to purge people from the rolls, particularly minorities and the poor who tend to vote Democratic. Supporters say voters are given plenty of chances to keep their active status and that the rules adhere to federal law requiring states to maintain accurate voter rolls.

Democrats and voting rights groups have expressed concern that other states will be emboldened by the ruling and adopt more aggressive tactics to kick voters off the rolls. In addition to Oklahoma, Georgia, Montana, Oregon, Pennsylvania and West Virginia have laws similar to Ohio's.
