[JURIST] The Ohio Republican Party has threatened to sue county elections boards that reject the party's voter registration challenges because the challenges were improperly filed. Franklin and other Ohio counties have rejected some of the GOP challenges to newly registered voters because the incorrect precinct for the voter was listed, but Ohio GOP Chairman Robert Bennett said that a voter's name and address should be enough to determine whether the voter lives where they are registered. Bennett also threatened court action against boards that take a different view. Ohio Secretary of State J. Kenneth Blackwell is expected to issue a directive Tuesday that will provide county boards guidelines on handling the challenges.
