After three failures, Ohio’s powerful political mapmaking body convened Tuesday…setting a series of meetings for hammering out a constitutional compromise on boundaries for state legislative districts. The Ohio Supreme Court has rejected three sets of Ohio House and Ohio Senate maps drawn by the panel, ruling in a 4-3 vote each time that the plans were unconstitutionally gerrymandered to unduly favor Republicans. Some GOP lawmakers have said they want to impeach Chief Justice, Maureen O’Connor, a moderate Republican who joined the court’s three Democrats in those decisions.
