History

Gerrymandering and Its Effects on Electoral Fairness

Quick fact

The efficiency gap, a metric for partisan gerrymandering, measures wasted votes—votes for losing candidates and votes beyond what the winner needs. A gap of just 2 seats in a 100-seat legislature can persist without flipping, meaning a party can lose the popular vote yet keep a majority.

Why this is interesting

How can a party win fewer votes yet still control the government? The answer lies not in the ballot box, but in the drawing of district lines.
