Roll Call offers this breaking news report (paid subscription required). A snippet: “Republicans, who now have unified control of state government, sought to change the current map, drawn by Democrats in 2001, because they argued the boundaries were unfairly drawn to produce partisan gains. They say their new map, drawn by a Westmoreland aide, splits fewer precincts and counties and reunites communities of interest. Democrats, meanwhile, have called the virtually unprecedented mid-decade action a GOP power grab and have threatened a court challenge.” The change will need to be precleared under Section 5 by the Justice Department.
