Whether they are running for an office at the top of the ballot or the bottom, incumbents hold significant advantages when they run for re-election. These advantages include higher name recognition, more experience and any accomplishments they have attained in their past years in office. They can use these advantages to promote their campaigns and gain trust with voters. In order to win, challengers must show voters not only that they are qualified for the position, but also that they can serve better than the current officeholder.

Over the past 10 election cycles, an average of86.1 percent ofU.S. Senate incumbents were re-elected to their seats. Easily surpassing them are the94.2 percent ofU.S. House incumbents who have retained their seats since 1996.^[1] Over90 percent of state legislative incumbents won re-election every year since 1996. In 2015,88.41 percent of municipal incumbents won re-election inAmerica's largest cities.

Ballotpedia conducted the following study using data from the 2015 elections to investigate the advantages of incumbency in school board elections.

Comparing to 2014

Incumbents in the2015 school board elections saw very similar success rates to those seen in the2014 school board elections. In 2014, 81.31 percent of incumbents won another term on their respective school boards. In 2015, 82.66 percent were elected to additional terms.

Though incumbents experienced similar success rates each year, those who ran in 2014 kept a larger percentage of the seats on the ballot. A total of 61.44 percent of seats on the ballot in 2014 were retained by incumbents, compared to 58.17 percent in 2015. This discrepancy comes in part from how many more seats were on the ballot in 2014 than in 2015. In 2014, 2,190 seats were up for election, and 1,654 incumbents ran to retain their seats. In 2015, 1,377 seats were up for election, and 969 incumbents ran to keep their seats.

In 2015, 40.45 percent of incumbents ran unopposed. This was higher than the 35.85 percent of incumbents who ran unopposed in 2014. A total of 70.88 percent of incumbents who faced challengers won additional terms in 2015. This was equal to the 70.88 percent of incumbents who successfully defeated challengers to keep their seats in 2014.

Methodology

This report looks at overall numbers from the 2015 school board elections related to incumbency success in thetop 1,000 school districts in the United States by enrollment. Of those districts, 440 heldschool board elections. These elections took place in 32 states. The 18 states where the largest districts by enrollment did not hold elections in 2015 wereAlabama,Arizona,Florida,Georgia,Hawaii,Indiana,Kentucky,Maine,Maryland,Michigan,Nevada,North Dakota,Rhode Island,Tennessee,Utah,Vermont,West Virginia andWyoming. These states are not included in this report.

The elections in the 2015 scope were not equally divided across states. The range runs from a high of 218 school board seats on the ballot inTexas to a low of one seat on the ballot inMississippi. The comparisons made in the report are not representative of each state as a whole; rather, they demonstrate the relative incumbency success rates among the largest districts of each state, with varying sample sizes in each location. To mitigate the unequal representation by state, this report also looks at incumbency success rates by enrollment size. School districts were compared by eight enrollment ranges, with the largest enrollment size at over 100,000 students and the smallest enrollment size below 10,000 students.

The total number of candidates includes a small number of duplicates as certain individuals ran for multiple seats. If that was the case, they were counted for each seat they ran to represent. To calculate the percentage of unopposed seats and the average number of candidates who ran per seat, this report counts only formal candidates. Candidates are considered formal candidates if they went through the regular filing process stipulated for school board elections in their state. Write-in candidates are not considered formal candidates as laws vary greatly across the states in how they file for election or if they have to file at all.

Because write-in candidates were not calculated as formal candidates, any incumbent who faced only write-in challengers was considered unopposed. No write-in candidate beat an incumbent to win a seat in 2015; they only took open seats. Incumbents were also considered unopposed if no formal candidate filed to challenge them who could actually defeat them. For example, if minor party requirements were used, and the number of minor party candidates equaled the number of seats required to be filled by a minor party representative, those minor party candidates were considered unopposed. Incumbents were not considered unopposed if they faced any challenge throughout their election process. For example, if they saw opposition in aprimary election but not a general, they were not considered unopposed.

Success rates

Success rates for incumbents in 2015 varied depending on the method in which elections were conducted. For example, incumbents were more likely to run for re-election, run unopposed and retain their seats when they ran in races heldby district, compared to other election methods. The number of total candidates in a race also affected incumbents' success rates. They were nearly always more successful when running in races with three total candidates, compared to running in races with two, four or five or more candidates.

Incumbent success rates were also influenced by the partisan nature of the elections they ran in and by the election type, whether it was aprimary, a general or arunoff.

Overall, 84.62 percent of incumbents in that enrollment size won additional terms, and 77.78 percent of incumbents who faced challengers kept their seats.
