Episode notes
How Gerrymandering Works
- Gerrymandering exploits the winner-take-all nature of the US electoral system.
- By "packing and cracking" voters, minorities can be strategically underrepresented.
Redistricting Rules
- Redistricting rules vary by state and often lack prioritization.
- Universal rules include population balance and racial fairness, while other rules cover district contiguity, compactness, political boundaries, and communities of interest.
Segregation Paradox
- Residential segregation, typically negative, can paradoxically benefit minority representation.
- Clustered minorities have a better chance of controlling districts than uniformly dispersed ones.
