From Ballotpedia There were 220 seats in two states with a general election in 2013. We took a look at each of the states to see how many state legislative incumbents who chose to run for re-election in 2013 did not face a primary challenger.
Our main findings:
Because only two states held elections in 2013, the sample size is small when conducting analysis. It is therefore helpful to compare the states holding elections in 2013 to the 44 states that held elections in 2012. Here is how the four states would have ranked in 2012, based on the percentage of incumbents with no primary challenger.
| State | Senate at stake | Senate without primary challenge | House at stake | House without primary challenge | Total without primary challenge | % without primary challenge |
|---|---|---|---|---|---|---|
| New Jersey | 40 | 33 | 80 | 64 | 97 | 85.1% |
| Virginia | -- | -- | 100 | 93 | 93 | 93.0% |
| State | Senate at stake | Senate without primary challenge | House at stake | House without primary challenge | Total without primary challenge | % without primary challenge |
|---|---|---|---|---|---|---|
| Louisiana | 39 | 18 | 105 | 48 | 66 | 61.7% |
| Mississippi | 52 | 33 | 122 | 80 | 113 | 76.9% |
| New Jersey | 40 | 31 | 80 | 49 | 80 | 81.6% |
| Virginia | 40 | 34 | 100 | 85 | 119 | 98.3% |
