There were 6,065 state legislative seats up for election on November 6, 2018, in 46 states. This page analyzes contested primaries in those races. A primary is contested when there are more candidates running than nominations available, meaning at least one candidate on the primary ballot must lose. Learn more about the terms and methodologies used in this analysis.

Ballotpedia uses the number and percentage of contested primaries to help determine the overall competitiveness of an election cycle. A greater number of contested primaries indicates more candidates running for office and more choices voters must make. A smaller number of contested primaries indicates fewer candidates and choices on the ballot.

There were 5,572 state legislative districts up for election nationwide, creating 10,897 possible primaries. Of that total, there were 2,123 contested primaries, meaning 20% of all primaries were contested. This was the highest number and percentage of contested primaries since Ballotpedia began gathering data in 2010.

    Primary

    See also: Primary election

    A primary is an election used either to narrow the field of candidates or to determine political parties' nominees in advance of a general election. Broadly, a state might use one of two types of primary systems for its state legislative elections: partisan or top-two/four.

    Partisan primaries

    See also: Open, closed, and semi-closed primary

    Partisan primaries are those where candidates from the same party compete against one another. The winning candidates receive their parties' nominations in order to appear on the general election ballot.

    Top-two/four primaries

    See also: Top-two primary and Top-four primary

    Top-two/four primaries are those where all candidates, regardless of their party affiliations, appear on the same primary ballot. Depending on the system in place, either the top-two or top-four vote-getters advance to the general election.

    Contested primary

    A contested primary is one where there are more candidates running than nominations available, meaning at least one candidate on the primary ballot must lose.

    The number of candidates needed to create a contested primary depends on the primary system in place and the number of seats up for election in a state legislative district.

    In states with partisan primaries, a primary is typically contested when two or more candidates from the same political party file to run since only one candidate can receive their party's nomination. In states with multi-member state legislative districts, the number of candidates a party can nominate to the general election ballot depends on the number of seats in the district. In these cases, a primary is contested when at least one more candidate files to run than there are seats in the district. In states with top-two/four primaries, a primary is contested when more than two (in states with a top-two system) or more than four (in states with a top-four system) candidates file to run.

    Possible primaries

    The number of possible primaries is determined by the number of districts holding elections and the primary system in place.

    In states with partisan primaries, there are two possible primaries per district, one for each of the two major parties. In states with top-two/four primaries, there is one possible primary per district, since every candidate appears on the same primary ballot.

    Methodology

    This page analyzes the total number of contested state legislative primaries by comparing the number of such primaries to the number of possible primaries.

    Ballotpedia considers a primary as contested when there are more candidates on the ballot than nominations available. If a candidate unofficially withdraws before the primary but remains on the ballot, that candidate is included in the total towards determining whether a primary is contested.

    In states with partisan primaries, only major party candidates and primaries are counted. In states with top-two/four primaries, all candidates—major party and otherwise—are counted.

    If a district uses a convention—a nominating contested reserved to a smaller number of participants usually referred to as delegates—as the sole means of nominating a candidate, that district is not included in the calculation of possible primaries. In 2018, no state legislative districts used conventions as the sole means of nomination. Two states—Connecticut and Utah—used a convention-primary system, where candidates could be nominated via a convention but, in both states, those contests still could have advanced to a primary.
