Redistricting is the process of redrawing the boundaries of electoral districts, typically occurring every ten years after the census. This process is crucial for ensuring that each district has roughly equal populations, maintaining the principle of one person, one vote. Redistricting can significantly impact political representation, as the way districts are drawn can advantage or disadvantage particular political parties (known as gerrymandering). By altering district lines, political entities can shape electoral outcomes, affecting which candidates have a better chance of winning in subsequent elections.
