Deviations in two elections

[edit]

The following 95 counties have deviated from the winner of the presidential election in two elections since 1980:[2]

Comparision with random distribution

[edit]

The 125 bellwether counties have had 85% accuracy over the course of 44 years. While this might seem impressive, it's not. The 125 most accurate bellwether counties from a 50/50 distribution would have an accuracy of 80%, but since the winner of the presidential elections from 1980 on got about 53.1% of votes (excluding third parties), the best comparison would be a random distribution with 53.1% accuracy, making the accuracy 84%.
