Redistricting Across States

The Constitutional mandate to redraw electoral district lines follows the decennial Census, as we learn where we, the people, live.

In 2025-26, five states (CA, FL, NC, TN, TX) redrew congressional lines without a court order. So far. (In IN, MD, and SC, the state Senate said no; in VA, the courts said no.; in MO, the courts said wait.)
