Ohioans to vote on controversial constitutional amendment in August.

Ohio Republicans have approved a resolution that will ask voters in August to increase the threshold needed to change the state's constitution from a simple majority to 60%, and require backers of ballot initiatives to get signatures from voters in all of Ohio's 88 counties. This could make it more difficult for abortion-rights supporters to pass a measure in November that would guarantee Ohioans' access to abortion. Critics say the move is part of a broader campaign by opponents of abortion to thwart citizen-approved ballot measures enshrining abortion rights.
