Lawsuits are accumulating against Ohio’s new congressional map, just as they did for GOP-drawn maps of new legislative districts, as voting and civil-rights groups allege partisan gerrymandering against the state’s ruling Republicans. The latest suit comes from the Ohio arms of the League of Women Voters and the A. Philip Randolph Institute…on behalf of a group of voters. The groups’ lawyers told the Ohio Supreme Court in a filing this week…that it is indisputable that the 15-district map of U.S. House districts unduly’ favors the Republican Party.
