Early voting is underway in Virginia on a closely watched redistricting referendum that is shaping up to be a razor-thin race, with both parties increasingly treating the April 21 vote as a pivotal and unpredictable fight for control of the House.

The ballot measure would temporarily return map-drawing authority to the Democratic-controlled legislature, which has already passed a new congressional map to be used for 2026, 2028, and 2030, pending legal challenge. The new map shifts Virginia’s 6-5 Democratic majority to 10-1 in favor of Democrats.
