There were 6,125 state legislative districts, in 46 states, with a seat up for election on November 2, 2010. 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.
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 3,852 (77.3%) of those 4,985 districts, the incumbent faced no challenger in the primary.
- Thus, only 1,133 (22.7%) of incumbents faced a primary opponent.
- Of those 1,133 incumbents who faced a primary, only 96 were defeated.
- North Dakota, Colorado, Connecticut, Maine and Minnesota had the fewest incumbents facing primary opposition -- in other words, these five states had the least amount of competitiveness at the primary level.
- The five states with the most competitive primaries in terms of incumbents facing primary 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 was one of 3 factors used in evaluating which states had the highest, and which states had the lowest, overall competitiveness in the 2010 state legislative elections.
Additionally, we tracked incumbents that face no primary or general election opposition in the 2010 election. This data was not a primary component of the competitiveness index but was still compelling information regarding the elections.
There are 1,295 total incumbents (26.12%) who were guaranteed to win the race from the moment they registered for re-election -- because no opponent filed to run in the primary or general election.
States compared by primary competition
The state that was least competitive as defined by the percentage of its seats where the incumbent did not have a primary challenger in 2010 is defined as #46, while the state that was most competitive as defined by the percentage of its seats where the incumbent did have a primary challenger is defined as #1; that is, 1 = "most competitive", 46 = "least competitive".
