2019 Elections
Choose a chamber below:


On November 5, 2019, Democrats won majorities in the Virginia State Senate and the Virginia House of Delegates, while holding their majority in the New Jersey General Assembly. The victories in Virginia made the state a Democratic state government trifecta. Republicans held their majorities in the Mississippi State Senate and the Mississippi House of Representatives.

Seven of the country's 99 state legislative chambers held regular elections in 2019. These seven chambers represented 538 of the country's 7,383 state legislative seats (7.3%). This page contains information about regularly scheduled state legislative elections; click here to read about state legislative special elections in 2019.

Heading into the November 2019 general elections, Republicans held six of the seven chambers and 292 of the 538 seats (54.3%). Democrats held one chamber and 240 seats (44.6%).[1] Overall, Republicans controlled 61 of 99 legislative chambers (61.6%) and 3,863 of 7,383 state legislative seats (52.3%). Democrats controlled 37 chambers (37.4%) and 3,467 seats (47.0%).[2]

General elections in Mississippi, New Jersey, and Virginia took place on November 5, 2019. Louisiana also held a primary election on October 12, where candidates could win an election outright. In cases where no candidate won the primary outright, general elections in Louisiana took place on November 16, 2019. Louisiana and Mississippi held gubernatorial elections in 2019 as well.

These were the final elections in each of these state legislatures before the 2020 redistricting process. The legislators elected in 2019 will be responsible for the redistricting scheduled to occur after the 2020 census.

A Ballotpedia analysis of trifecta vulnerability in 2019 found the following:

  • Louisiana (Divided government) had a slight chance of becoming a Republican trifecta and a low chance of becoming a Democratic trifecta.
  • Mississippi (Republican trifecta) was a moderately vulnerable Republican trifecta.
  • New Jersey (Democratic trifecta) was a non-vulnerable Democratic trifecta.
  • Virginia (Divided government) had a moderate chance of becoming a Democratic trifecta and a moderate chance of remaining under divided government.

State government trifectas

See also: Gubernatorial and legislative party control of state government

Heading into the 2019 state legislative elections, Mississippi was a Republican trifecta, New Jersey was a Democratic trifecta, and Louisiana and Virginia were both under divided government. Kentucky was also a Republican trifecta but only held a gubernatorial election. The 2019 elections resulted in one additional Democratic trifecta and one fewer Republican trifecta—Virginia became a Democratic trifecta, while Kentucky became under divided government.

A trifecta is when one political party holds these three positions in a state's government:

The concept of the trifecta is important in state lawmaking because in many states, the governor, senate majority leader, and house majority leader play decisive roles in the legislative process.

Heading into the 2019 elections, 36 states were controlled by a trifecta. States with a trifecta included:

  • Democratic Party 14 Democratic trifectas
  • Republican Party 22 Republican trifectas

As a result of the 2019 elections, there were 21 Republican trifectas and 15 Democratic trifectas.

Battleground chambers

See also: Battlegrounds

Ballotpedia tracked three state legislative battleground chambers in 2019—the Louisiana House of Representatives, Virginia State Senate, and Virginia House of Delegates.

Party control of eight seats in the Louisiana state House was on the ballot in the November 16, 2019, general election. Had Republicans won all seven races where they were on the ballot, the party would have won a supermajority in the chamber.

Heading into the election, Republicans held a two-seat majority in both Virginia chambers. The Virginia State Senate has had a 2-seat or smaller majority (including several years as a tied chamber) since 2007. In the Virginia House of Delegates, Democrats picked up 15 seats in 2017, and only a Republican win in a tiebreaker of random chance in District 94 kept Republicans from losing control of the chamber.

Battlegrounds were chambers that we anticipated would be, overall, more competitive than other chambers and have the potential to see significant shifts in party control in the 2019 general elections.

Criteria for identification as a battleground chamber included the majority party's share of seats, the number of competitive races, and more. Read the complete list of criteria here.

The columns in the chart below list the following information:

  • Seats up in 2019: This was the number of seats in the chamber that were up for election in 2019.
  • Margin: This was the difference in seats between the majority and minority parties.
  • Majority share of seats: This was the percentage of the chamber's total seats controlled by the majority party.
  • Last time party control changed?: This was the election where the party in power before the 2019 elections took control of the chamber.

State legislative special elections

See also: State legislative special elections, 2019

In 2019, special elections for state legislative positions were held for the following reasons:

  • 47 due to appointment, election, or the seeking of election to another position
  • 21 due to a retirement
  • 6 due to the death of the incumbent
  • 1 due to a resignation related to criminal charges
  • 2 due to an election being rerun

Impact of special elections on partisan composition

The partisan breakdown for the special elections was as follows:

The table below details how many seats changed parties as the result of a special election in 2019. The number on the left reflects how many vacant seats were originally held by each party, while the number on the right shows how many vacant seats each party won in the special elections. In elections between 2011 and 2018, either the Democratic Party or Republican Party saw an average net gain of four seats across the country. Between 2017 and 2018, Democrats had a net gain of 19 seats.

Note: This table reflects information for elections that were held and not the total number of vacant seats.

Electoral competitiveness

See also: Annual State Legislative Competitiveness Report: Vol. 9, 2019

Ballotpedia's 9th Annual State Legislative Competitiveness Report analyzes the features of all 538 state legislative elections taking place in November 2019. Key findings include:

HIGHLIGHTS
  • 299 (55.6 percent) state legislative elections do not have major party competition; they feature a candidate from just one of the two major political parties.
  • There are more races with two major party candidates in 2019 (44.4 percent) than there were in 2015, but fewer than there were in 2011.
  • 103 (19.1 percent) state legislative incumbents are not seeking re-election. Of those, 62 (60.2 percent) are Republicans, 39 (37.9 percent) are Democrats, and two (1.9 percent) are Independents.
  • Only four states hold state legislative elections during odd-numbered years: Louisiana, Mississippi, New Jersey, and Virginia. This year, both chambers in Louisiana, Mississippi, and Virginia were up for election, along with the New Jersey General Assembly. The last time all of these chambers were up for election at the same time was 2015. The table below shows competitiveness statistics for each odd-year election dating back to 2011.

    Competitiveness between years: 2011 - 2019 (odd years)
    2011 2013 2015 2017 2019
    % Open seats 18.2% 6.8% 13.9% 8.6% 19.1%
    % Incumbents facing primary 20.1% 12.2% 21.8% 16.0% 30.1%
    % Races with both major parties 57.4% 73.6% 38.7% 80.9% 44.4%
    % Defeated incumbents 5.9% 2.9% 5.8% 7.0% 3.9%

    Seats without major party opposition

    See also: Major party candidates with major party competition in the November 2019 state legislative elections

    When a candidate from only one of either the Democratic or Republican parties runs for a state legislative seat, the seat is all but guaranteed to be won by that party. In 2019, 299 state legislative seats do not feature major party competition.

    • 158 state legislative elections (29.4 percent of all state legislative elections) did not feature a Democratic candidate and were likely to be won by a Republican. In other words, Democrats were contesting 70.6 percent of all state legislative seats.
    • 141 elections (26.2 percent of all state legislative elections) did not feature a Republican candidate and were likely to be won by a Democrat. In other words, Republicans were contesting 73.8 percent of all state legislative seats.
    • In two states, more than half of all candidates did not face major party competition.

    Open seats

    See also: Open seats in the 2019 state legislative elections

    In districts where the incumbent legislator does not file for re-election, the seat is guaranteed to a newcomer.

    • 103 state legislative incumbents are not running for re-election. In other words, nearly 20 percent of all state legislative seats won in the 2019 cycle were guaranteed to be held by a newly elected state legislator, the most since 2012.
    • 39 Democratic state legislators (37.9 percent of the total) did not seek re-election.
    • 62 Republican state legislators (60.2 percent of the total) did not seek re-election.
    • Two Independent state legislators did not seek re-election.

    Primary competitiveness

    Historical competitiveness data

    In 2010, Ballotpedia began using official candidate lists from each state to examine the competitiveness of every state legislative race in the country. Three factors are used in the analysis: the number of incumbents who do not seek re-election, the number of races that feature only one major party candidate, and the number of incumbents who draw primary challengers.

    The following table details the data collected from regularly scheduled state legislative elections between 2010 and 2018. It features the total number of seats up for election, open seats, races that included only one major party candidate, and incumbents who faced primary challengers. The table is organized by even-year elections and odd-year elections because years that have the same number of seats up for elections are similar in terms of their competitiveness.

    Odd-year elections since 2009

    Four states hold state legislative elections in odd-numbered years: Louisiana, Mississippi, New Jersey, and Virginia. In the last 10 years, there have been between two and eight state legislative chambers up in an election cycle. Only two chambers--the New Jersey General Assembly and the Virginia House of Delegates--hold regular elections every two years. The other six chambers hold elections every two to four years, depending on when the last round of redistricting took place.

    The chart below details the results of state legislative elections from 2009 to 2017. During that period, two chambers flipped party control--both in 2011.[18] Partisan changes ranged from a Republican gain of 27 seats in 2011 to a Democratic gain of 18 seats in 2017.

    Impact of term limits

    See also: Louisiana State Senate elections, 2019 and Louisiana House of Representatives, 2019

    In 2019, 47 state legislators were ineligible to run for office because of term limits. Louisiana was the only state holding elections for a term-limited legislature in 2019.

    Of the 15 state legislatures with term limits, Louisiana is the only state where term limits were imposed by the state’s lawmakers, rather than through the ballot initiative process. Under Louisiana’s term limits, state lawmakers can serve no more than three four-year terms. The state’s term limits law was enacted in 1995. The first year that term limits impacted the ability of incumbents to run for office was in 2007.

    Political context

    The 2019 elections occurred in the aftermath of significant Democratic gains in the 2018 elections and 2017 elections. In the 2018 elections, Democrats flipped a net 308 legislative seats and picked up six legislative chambers, reversing some of the Republican gains made from 2010 to 2016.

    Changes in chamber partisan control, 2010 to 2018

    See also: Partisan composition of state legislatures

    Prior to the 2010 elections, Democrats controlled 60 of the country's 99 state legislative chambers, Republicans controlled 37, and two chambers were not controlled by either party. In the six years that followed, Republicans made significant gains and took control of many of the chambers that were previously held by Democrats. After the 2016 elections, Democrats controlled 31 chambers and Republicans controlled 68.

    In the 2017 and 2018 elections, Democrats increased their number of state legislative chambers to 37, and Republicans saw their number of chambers fall to 61. Control of one chamber, the Alaska House of Representatives, was split between the parties.

    From 2010 to 2018, there were 61 instances where a state legislative chamber changed partisan control. Of these 61 changes, 40 involved a chamber changing from Democratic to Republican control and 17 involved a chamber changing from Republican to Democratic control. The other four involved chambers that were split between the two parties (Oregon House in 2010 and 2012; Montana House in 2010; Alaska House in 2018).

    Most of the changes came during major elections but some also came through special elections (Louisiana House in 2010; Washington Senate in 2017) and party switching (Louisiana House in 2010; Mississippi Senate in 2011). In some cases, the party that gained control did not have a numerical majority but instead controlled the chamber through a bipartisan coalition (i.e., Alaska House in 2016). This table does not account for changes in party control or ties in a chamber that lasted for less than one year and were not the result of a regularly scheduled election. An example of this is the brief period of Democratic control in the Virginia State Senate in 2014.[24]

    From 2010 to 2018, 39 chambers switched control: 24 switched control once, 11 switched control twice, one switched control three times, and three switched control four times.

    For this chart, a red box indicates that the chamber flipped from Democratic to Republican control, and a blue box indicates that the chamber flipped from Republican to Democratic control.[25]

    State legislatures and presidents

    First two years in office

    Heading into the 2019 election, the Republican Party was coming off a substantial loss of seats during a major election for the first time in more than a decade. Republicans across the country collectively lost 345 seats in 2017 and 2018, marking the third time during the last four presidencies that the party of the sitting president--Donald Trump (R) in this case--lost seats during that president's first midterm election. Democrats lost 702 seats during Barack Obama's (D) first two years in office and 488 seats during Bill Clinton's (D) first two years. Only George W. Bush (R) saw a net gain of seats during his first two years with Republicans winning a net 110 seats.




    Two-term presidents

    It is normal for a party to lose ground in state legislatures when their party controls the presidency for two terms. Between the time of Franklin Roosevelt (D) and George W. Bush (R), the political party of the president lost, on average, 450 state legislative seats while holding the White House. The losses that the Democratic Party sustained under Barack Obama (D), however, were exceptional, rivaled only by the terms of Richard Nixon (R) and Dwight Eisenhower (R), when Republicans lost 800 and 843 seats, respectively.

    Trifectas from 2010 to 2018

    See also: State government trifectas

    A state government trifecta occurs when one political party controls the primary levers of power in a state: the governor's office, the state Senate, and the state House. From 2010 to 2018, the Republican Party increased its number of trifectas and the Democratic Party saw a decline in its trifectas. However, Democrats picked up six trifectas in the 2018 elections, and Republicans lost four trifectas.

    This chart shows the number of trifectas each party held heading into elections from 2010 to 2018, and the number of trifectas following the 2018 elections.
