Historical party control

Legislative party competitiveness score

Professors of Political Science Gerald Gamm and Thad Kousser, University of Rochester and University of California San Diego, respectively, claim that states with competitive party systems spend more on education, health, and transportation. They base this on a study of each state's party competitiveness from 1880 (or year of statehood) to 2010. They assigned each state legislature a competitiveness score, which "can range from 100% if the two parties are evenly matched to 0% if one party holds every seat in a legislature."^[2]

The below chart shows the state's legislative party competitiveness score from 1880 to 1990. The chart offers a look into competitiveness prior to Ballotpedia's 1992 analysis.
