There are 6,125 state legislative districts with a seat up for election on November 2, 2010, in 46 states. We took a look at each of the 46 states to see how many state legislative incumbents who chose to run for re-election in 2010 faced a primary challenger.
The state that is least competitive as defined by the % of its seats where the incumbent did not have a primary challenger in 2010 is defined as #46, while the state that is most competitive as defined by the % of its seats where the incumbent did have a primary challenger is defined as #1; that is, 1 = "most competitive", 46 = "least competitive".
Our main findings:
- The incumbent chose to run for re-election in 4,985 (81.4%) of the 6,125 districts holding state legislative elections in 2010.
- In 3,861 (77.31%) of those 4,985 districts, the incumbent faced no challenger in the primary.
- Adjusting for open seats (1,140 districts where no incumbent is running), there are
- North Dakota, Colorado, Connecticut, Maine and Minnesota have the fewest incumbents facing primary opposition.
- The five states with the most competitive primaries in terms of incumbents facing challengers are New Hampshire, Maryland, Nebraska, West Virginia and Arizona.
The score that states received based on their ratio of incumbents facing a primary challenger is one of 3 factors used in evaluating which states have the highest, and which the lowest, overall competitiveness in the 2010 state legislative elections.
