Virginia is projected to get a 12th U.S. House seat after the 2020 U.S. census, according to demographers at the University of North Carolina, which portends continued upheaval over the state’s district boundaries. A 12th U.S. House seat would give Virginia its largest congressional delegation since the 1850s, when the state had 13 representatives and it still included the territory now known as West Virginia, said Larry Sabato, head of the Center for Politics at the University of Virginia.
