State legislatures compared by extent of electoral competitiveness in 2010
This chart captures the ranking that a state legislature received on all three factors in this Election Competitiveness Index.
- The first column, "Primary Contests," ranks states against each other based on the percentage of incumbents who had a primary challenger.
- The second column, "Major Party Competition," ranks states against each other based on the percentage of major party candidates on the November 2 ballot with a major party challenger.
- The third column, "Open Seats," contrasts states based on the percentage of incumbents who ran for re-election in 2010.
- The fourth column is an arithmetical average of the state's scores on the all three factors.
