Eighty-six state legislative chambers held regularly-scheduled elections in 2020. Ballotpedia identified 24 of those chambers as state legislative battlegrounds. Heading into the 2020 elections, Republicans controlled 15 battleground chambers and Democrats controlled eight. Control of the Alaska House of Representatives was split under a power-sharing agreement, although Republicans had a 21-15 majority.

In 2018, 87 state legislative chambers held regularly-scheduled elections. Ballotpedia identified 22 of those chambers as battlegrounds. Democrats gained control of six Republican-held battleground chambers (the Colorado State Senate, Maine State Senate, Minnesota House of Representatives, New Hampshire State Senate, New Hampshire House of Representatives, and New York State Senate). Republicans entered into a power-sharing agreement in the Alaska House of Representatives, which had previously been under control of the Democratic minority.

Ballotpedia identified the following state legislative chambers as 2020 battlegrounds:

Overview[edit]

Of the 86 chambers that held regularly-scheduled elections in 2020, Ballotpedia identified 24 battleground chambers in 17 states. We anticipated that these chambers would be more competitive overall and had the potential to see major shifts in party control. Four of those chambers (the Arizona House of Representatives, Georgia State Senate, Georgia House of Representatives, and Nebraska State Senate) were not battleground chambers at any point in the preceding decade.

The columns in the chart below list the following:

Seats up in 2020: This was the number of seats that were up for election in 2020.
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 seats controlled by the majority party.
Last time party control changed: This was the election where the majority at the time of the 2020 elections took control of the chamber.

State-by-state breakdown[edit]

This section gives an overview of each of the 23 battleground chambers in 2020 and explains what criteria each chamber met to make our list.

Why were these chambers highlighted?[edit]

Ballotpedia’s approach to determining what is and is not a battleground chamber relied on a series of criteria, with exceptions made in specific outlying cases. Ballotpedia scored the competitiveness of each state legislative chamber holding elections in 2020, with each of the following criteria being worth 1 point:

Three or fewer seats needed to flip to change control of the chamber.
15% or less of the seats up for election in 2020 needed to flip to change control of the chamber.
15% or more of the seats up for election in 2020 were decided by a margin of 10% or less the last time they were up for election.
10% or more of the seats up for election in 2020 changed partisan control the last time they were up for election.
The number of seats up for election in 2020 that changed partisan control the last time they were up was greater than the number of seats that needed to flip to change control of the chamber.
The chamber was a battleground chamber in 2018.
A battleground gubernatorial election took place in the same state in 2020.
The chamber flipped two or more times between 2010 and 2020.

These criteria were combined with the Cook Political Report's state legislative race ratings.^[2]

Partisan control
Although Republicans won a 23-16 majority with one independent in the 2018 elections, a coalition of 15 Democrats, four Republicans, and two independents elected Bryce Edgmon (I) as House speaker on February 14, 2019. The parties split control of key leadership positions and committees. Edgmon was elected speaker after leaving the Democratic Party. In an interview with the Anchorage Daily News which explored the formation of the coalition, Edgmon said, "It’s not issues that are separating us. At this point, I think it’s more party politics."^[3] Read more here.

What was at stake?

Republicans needed to gain two seats to win a majority, either by defeating Democratic or independent legislators in the general election or by defeating Republican members of the majority coalition in the primary election.

If Republicans had flipped the chamber while retaining control of the state Senate, they would have gained a state government trifecta. If Democrats maintained the split coalition or gained a majority, they will have preserved the state's divided government status.

Why was it a battleground?

Power-sharing agreement: The power-sharing agreement agreed to following the 2018 elections involved a coalition of all 15 Democrats, both independents, and four of the 23 Republicans, who together comprised a 21-19 majority. The defeat of two coalition members would have caused the coalition to lose its majority.

Seats needed to flip: Democrats needed to flip five of the 40 seats up for election (13% of the chamber) in order to win control of the chamber.

2018 battleground: The Alaska House of Representatives was a battleground chamber in 2018. That year, Republicans gained two seats from Democrats and one from an independent. The chamber's Democratic-led minority coalition was replaced by a power-sharing agreement. Read more about the 2018 elections here.

History of recent flips: The Alaska House of Representatives flipped twice between 2010 and 2020; Democrats gained control of the chamber in 2016, and control passed to a power-sharing agreement in 2018.

Race ratings: The Cook Political Report rated the Alaska House of Representatives a toss-up in 2020, meaning both parties had a good chance of winning control of the chamber.^[4]

Historical party control[edit]

A multipartisan governing coalition has controlled the Alaska House of Representatives since 2016. These coalitions primarily consisted of Democrats and independents after the 2016, 2018, and 2020 elections. Following the 2022 elections, it consisted primarily of Republicans. After the 2024 elections, the coalition returned to a Democratic majority.

After the 2018 elections, Republicans held a 30-18 majority with one legislator unaffiliated.

There are no formal party alignments or groups within the Nebraska State Senate. Coalitions tend to form issue-by-issue based on a member's philosophy of government, geographic background and constituency. However, almost all of the members of the legislature are affiliated with the state affiliate of either the Democratic or the Republican Party and both parties explicitly endorse candidates for legislative seats. Senators and candidates are listed as officially nonpartisan, but in most cases the individual has a direct party affiliation. As an example, in most cases if a sitting senator runs for Congress, the individual runs on either the Democratic or Republican line on the ballot.

Political context[edit]

The 2020 state legislative elections took place in the context of significant Republican gains in state legislatures between 2010 and 2017 and a swing back towards Democratic control in 2018. Between 2010 and 2017, Democrats lost a net 968 seats across the country's 99 state legislative chambers. Democrats gained a net 308 seats in the 2018 state legislative elections. In the 2019 elections, Republicans gained a net 12 seats while Democrats gained a net one seat. Democrats flipped two legislative chambers.

Heading into the 2020 elections, Republicans held 21 state government trifectas to Democrats' 15, majority control of 59 state legislative chambers to Democrats' 39, and control of 26 governors' offices to Democrats' 24.

Changes in chamber partisan control, 2010 to 2019[edit]

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, 2018, and 2019 elections, Democrats increased their number of state legislative chambers to 39, and Republicans saw their number of chambers fall to 59. Control of one chamber, the Alaska House of Representatives, was split between the parties.

From 2010 to 2019, there were 63 instances where a state legislative chamber changed partisan control. Of these 63 changes, 42 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.^[34]

From 2010 to 2019, 40 chambers switched control: 24 switched control once, 12 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.^[35]

State legislatures and presidents[edit]

First midterms[edit]

Heading into the 2020 election, the Republican Party was coming off a substantial loss of seats during an even-year election for the first time in more than a decade. Republicans across the country collectively lost 349 seats during the 2018 state legislative elections and 2017 state legislative elections, 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 midterm and 488 seats during Bill Clinton's (D) first midterm. Only George W. Bush (R) saw a net gain of seats during his first midterm with Republicans winning 110 seats.

Two-term presidents[edit]

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 2019[edit]

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. In the 2019 elections, Democrats gained one trifecta and Republicans lost one.

This chart shows the number of trifectas each party held heading into elections from 2010 to 2018, and the number of trifectas following the 2019 elections.

Trifectas by year: 2010-2018

[38] Chamber went from being controlled by a Democratic-led bipartisan coalition to being led by a coalition with power split between the parties.

[39] The chamber changed partisan control prior to the 2011 elections due to Democrats switching to the Republican Party and special election wins by Republicans. Republicans increased their majority in the 2011 elections to 31-21.

[41] In the 2011 elections, the chamber changed from a 22-18 Democratic advantage to a 20-20 tie. Republicans effectively controlled the chamber because Lieutenant Gov. Bill Bolling (R) could cast tie-breaking votes.

[42] This chamber did not hold elections in 2010. It switched partisan control in December 2010 when Democrat Noble Ellington changed his party affiliation to Republican. In the regularly-scheduled 2011 elections, Republicans increased their majority to 58-45.
