With the passage of the Virginia map, Democrats had mostly succeeded in reaching a draw with Republicans in the redistricting wars. But with the Virginia map overturned and Southern states—including Tennessee, Louisiana, Alabama, and South Carolina—rushing to pass new maps before the midterms, Democrats could face a four to five-seat disadvantage heading into November, according to Amy Walter of the Cook Political Report. While that is not insurmountable in a wave election—and Democrats could still pick up two seats in Virginia under the existing map—it gives Democrats little margin for error in the effort to take back the House.
