Ballotpedia uses the number and percentage of incumbents in uncontested general elections to help determine the overall competitiveness of an election cycle. A larger number of uncontested general elections indicates less competitiveness because there are fewer opportunities for voters to elect a non-incumbent to office. A smaller number indicates more of those opportunities.

There were 911 Democratic incumbents in uncontested general elections, representing 43.0% of all Democratic incumbents who ran in the general election, a 1% decrease from 2014.

Terms and definitions

Incumbent

See also: Incumbent

Ballotpedia defines incumbency by chamber. Under this definition, if an incumbent in House District 1 filed for re-election in House District 2, they would still be counted as an incumbent due to their remaining in the same chamber even though they ran for a different seat. If an incumbent in House District 1 filed to run in Senate District 2, they would not be counted as an incumbent in the Senate race since they are coming from a different chamber.

Ballotpedia uses the term re-elect to refer to any incumbent who is running in an election to retain their office, including incumbents who were originally appointed to their position.

Uncontested general election

See also: General election

An uncontested general election is one where there is one candidate running, meaning the candidate will automatically win the election.

Methodology

Candidacy withdrawals

See also: Signature requirements and deadlines for 2016 state government elections

In order to have their names printed on election ballots, candidates must submit information prior to a filing deadline. Filing deadlines are the dates by which candidates must submit required paperwork to state election administrators.

For major party candidates, filing deadlines always precede primaries. However, candidates may choose to withdraw before the primary or general takes place. Withdrawals include decisions to leave the race, disqualifications, and deaths. These withdrawals are either official or unofficial.

An official withdrawal means the candidate withdrew before a specific date set in state law and their name was removed from the primary or general ballot. If an incumbent officially withdrew before the general election, they are not included in any of the totals of this analysis, unless they later re-entered the race as a minor party or independent candidate.

An unofficial withdrawal means the candidate withdrew after a specific date set in state law, typically after ballots have been printed, meaning their name remains on the ballot even though they are not actively campaigning. If an incumbent unofficially withdrew, they are included in the totals of this analysis.
