Major party competition in state legislative elections, 2016

Last updated on November 18, 2024

There were 5,916 state legislative seats up for election on November 8, 2016, in 44 states. Of that total, 2,508 (42%) were uncontested and had no major party competition. The remaining 3,408 (58%) were contested by both major parties. The number of seats with no major party competition was less than in 2014 (2,584) but more than in 2010 (2,142) and 2012 (2,384).

A seat has major party competition when candidates from both major parties are on the general election ballot. When only one major party is running for a seat, it has no major party competition and is effectively guaranteed to the major party candidate on the ballot. Learn more about the terms and methodologies used in this analysis.

Ballotpedia uses the level of major party competition to help determine the overall competitiveness of an election cycle. A larger number of seats without major party competition indicates fewer options on the ballot. A smaller number indicates more options.

Terms and definitions

Major party competition

Major party competition exists when candidates from both major parties—Democratic and Republican—appear on the general election ballot for a given seat.

A seat lacks major party competition when at least one major party does not have a candidate on the ballot, effectively guaranteeing the seat to the other major party. This includes cases where no candidates from either major party appear on the ballot, guaranteeing that seat to a minor party or independent candidate.

Seat

State legislative seats represent the total number of candidates who can be elected. These totals may differ from state legislative districts.

In most states, every state legislative district includes a single seat. These are referred to as single-member state legislative districts.

Certain states have multi-member state legislative districts, where a single district contains multiple seats.

Methodology

Counting major party competition

Major party competition is counted by seat.

In a single-member district, major party competition exists when one Democrat and one Republican appear on the general election ballot.

In multi-member districts, major party competition might exist for some seats while not existing for others.

For example, in a district with three seats, if three Democrats and two Republicans appear on the general election ballot, two seats have major party competition, while one does not. This is because the number of Republicans on the ballot is less than the number of seats up for election, meaning, at most, Republicans could win two of the three seats with the remaining seat effectively guaranteed to be won by a Democrat.

Major party competition is counted at the time of the general election. In states with top-two/four primaries, where every candidate appears on the same primary ballot regardless of political affiliation, this means only those candidates who advanced to the general election are counted. For example, if two Republicans and one Democrat ran in a top-two primary, and the two Republicans advanced to the general election, that seat is considered to have no major party competition since only one major party appears on the general election ballot.

Candidacy withdrawals

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

Candidates may choose to withdraw before the general election 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 general election ballot. If a major party candidate officially withdraws before the general election, the number of seats without major party competition increases unless another candidate replaces them.

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 a major party candidate unofficially withdraws before the general election, major party competition figures are unchanged.

Minor party and independent candidates

This analysis does not account for the presence of minor party and independent candidates on the general election ballot when determining major party competition.

For example, if a Republican candidate is on the general election ballot running against an independent candidate, that seat is not considered to have major party competition, since no Democratic candidates are present.

This is why seats contested by only one major party are referred to as guaranteed to the major party with a candidate on the ballot. While minor party and independent candidates can win state legislative elections, it is rare. Heading into the 2016 elections, minor party or independent legislators held 1% of the nation's 7,383 state legislative seats.

Major party write-in candidates

Most states allow voters to write in the name of some other candidate when casting a ballot. Write-in candidates affiliated with a major party are not accounted for when determining major party competition unless that write-in candidate wins the general election. In these instances, major party competition figures are updated retroactively.

Calculating the total number of seats contested by a party

While this analysis does not focus on the total number of seats each major party contested, those totals can be calculated using the information above.

• The total number of seats contested by Democrats is equal to the total number of seats with only Democrats on the ballot plus the number of seats contested by both major parties.
• The total number of seats contested by Republicans is equal to the total number of seats with only Republicans on the ballot plus the number of seats contested by both major parties.
