Democrats in New York proposed a new congressional map Sunday that could eliminate half of the state’s Republicans in the House of Representatives.

The new lines give Democrats an advantage in 22 of the state’s 26 congressional districts ahead of November’s midterm elections. Despite their advantage, however, the map may be less aggressive than what some Democrats, including lawyer Marc Elias, previously supported.

The map comes amid a battle for control of the House, with Democrats hoping to preserve their narrow advantage while Republicans target over two-dozen Democratic seats. While New York’s map helps Democrats keep their majority, it could be offset by likely Republican-advantaged maps in Texas, Florida and Georgia.
