Ohio’s newly drawn map of congressional districts…is hit with its first constitutional challenge…which claims the boundaries represent partisan gerrymandering by Republicans. A lawsuit is filed in the Ohio Supreme Court by the National Democratic Redistricting Committee’s legal arm…on behalf of a group of Ohio voters. Its legal action challenges a final map of U.S. House districts that passed through the Ohio Statehouse last week…without Democratic support. The governor then signed it over the weekend. Because of that lack of support from Democrats, the map will hold for just four years, rather than the typical 10. The lawsuit contends the map leans 12-3 in favor of Republicans, though the GOP describes it as 6-2, with the remaining seven districts being competitive.
