State Congressional Redistricting Process
The increasing prevalence of partisan gerrymandering has led to a landscape of legislative maps where many lawmakers choose their voters, rather than the voter choosing their lawmaker as intended. Some states have enacted policies to prevent gerrymandering by requiring legislative maps to be drawn by independent commissions rather than the legislatures themselves. This map tracks policies that govern congressional redistricting processes within the states.
