Ohio’s new congressional district map has cleared the Republican-controlled state legislature at a breakneck pace and is headed to GOP Governor Mike DeWine, who is under pressure to veto it.

The map’s latest iteration emerged late Monday and passed through two committees and two chambers in less than three days.

Because it lacks Democratic support, it is on track to last only four of the 10 years until the next census, which provides the population data needed for the map-drawing process.

Republicans call the new map competitive, constitutional and not unduly favorable to either party.

Democrats, voting-rights groups and scholars say the map is gerrymandered.
