Democrats maintained a supermajority in the 2018 elections for the Oregon State Senate. After the election, Democrats controlled 18 seats to Republicans' 12. A total of 17 seats out of the chamber's 30 were up for election on November 6, 2018.[1] Before the election, Democrats held a 17-13 majority.
The Democratic Party maintained a trifecta in Oregon after the 2018 elections by keeping control of the state Senate, state House, and governorship.
Because state senators in Oregon serve four-year terms, winning candidates in this election served through 2022 and played a role in Oregon's redistricting process. In Oregon, the state legislature is primarily responsible for drawing both congressional and state legislative district lines. Read more below.
Oregon state senators serve staggered, four-year terms and half of the Senate is up for election every two years.
The Oregon State Senate was one of 87 state legislative chambers with elections in 2018. There are 99 chambers throughout the country.

Margins of victory
A margin of victory (MOV) analysis for the 2018 Oregon State Senate races is presented in this section. MOV represents the percentage of total votes that separated the winner and the second-place finisher. For example, if the winner of a race received 47 percent of the vote and the second-place finisher received 45 percent of the vote, the MOV is 2 percent.
The table below presents the following figures for each party:
- Elections won
- Elections won by less than 10 percentage points
- Elections won without opposition
- Average margin of victory[2]

Process to become a candidate
For major party candidates
See statutes: Chapter 249, Sections 020, 068 and 056 of the Oregon Revised Statutes
A major party candidate can gain access to the ballot via one of two methods: by paying a filing fee or by filing a nominating petition.
Filing fee
A candidate of a major party can have his or her name printed on the ballot by filing a declaration of candidacy with the Oregon Secretary of State and paying the requisite filing fees. Filing fees are as follows:[4][5][6]
| Filing fees for major party candidates in Oregon | |
|---|---|
| Office sought | Fee |
| United States Senator | $150 |
| Governor, secretary of state, treasurer, attorney general, labor and industries commissioner, United States Representative | $100 |
| State senator and state representative | $25 |
Nominating petition
A candidate of a major party can have his or her name printed on the ballot by filing a nominating petition with the Oregon Secretary of State. Signature requirements are as follows:[7]
| Petition signature requirements for major party candidates in Oregon | |||||||
|---|---|---|---|---|---|---|---|
| Office sought | Required signatures | ||||||
| United States Representative | The lesser of 1,000 signatures or 2 percent of the number of votes cast in the district for president by members of the candidate's party* | ||||||
| Governor, secretary of state, treasurer, attorney general, United States Senator | The lesser of 1,000 signatures or 2 percent of the number of votes cast for president by members of the candidate's party** | ||||||
| State senator and state representative | The lesser of 500 signatures or 2 percent of the number of votes cast in the district for president by members of the candidate's party*** | ||||||
| *"Signatures must be obtained from 5 percent of the precincts in one-fourth of the counties in the congressional district." **"Signatures must be obtained from at least seven counties and be comprised of electors from 5 percent of the precincts in each of those counties." ***"If the district is within one county, signatures must be obtained from 10 percent of the precincts. If the district is in more than one county, signatures must be obtained from at least two counties and be comprised of electors from 6 percent of the precincts in each of those counties." | |||||||
For minor party candidates
Recognized minor parties (as defined in this article) are not permitted to participate in primary elections and instead must select candidates by nominating convention.
For unaffiliated candidates
An unaffiliated candidate can gain access to the ballot via one of two methods: nomination by individual electors or nomination by an assembly of electors.
Nomination by individual electors
See statutes: Chapter 249, Section 740 of the Oregon Revised Statutes
An unaffiliated candidate must submit the appropriate filing form with the Oregon Secretary of State and obtain approval to circulate the nominating petition prior to collecting signatures. Once approval has been obtained, circulators must gather signatures equal to at least 1 percent of the total votes cast for all candidates for presidential electors in the most recent general election within the electoral district for which the nomination is being sought.[8]
The Oregon Secretary of State does not calculate in advance the number of signatures required for each office. Instead, the number of required signatures is determined when candidates obtain approval to circulate nominating petitions.[9][10]
Nomination by assembly of electors
See statutes: Chapter 249, Section 735 of the Oregon Revised Statutes
An unaffiliated candidate must submit a candidate filing form signed only by the candidate. Upon receipt of the form, the Oregon Secretary of State will review the document and provide approval to organize an assembly of electors. The candidate must coordinate with the secretary of state to determine the time of the assembly. Once scheduled, notice of the assembly must be published at least once in at least three newspapers of general circulation in the electoral district in which the assembly seeks to nominate candidates. The notice must include the time and place of the assembly, offices for which nominations will be made, and the names and addresses of at least 25 active registered voters who want the assembly held and who are eligible to participate.[11]
Final approval to convene the assembly is granted once the candidate files a copy of the published notice with the secretary of state. An affidavit verifying that notice of the assembly was published in accordance with statutory requirements must be included with the copy of the notice. This affidavit must be signed by the newspaper's owner, editor, publisher, manager, advertising manager, principal clerk of one of the aforementioned, or the printer. The secretary of state will provide a written approval to convene the assembly. This formal approval document will include a petition number, the number of signatures required, the filing deadline, and a signature sheet template.[12][13]
The assembly itself must meet the following requirements:[12]
- The assembly must be held in one day in one location and must be completed within 12 hours.
- Assembly participants must be active registered voters within the electoral district from which the assembly is nominating candidates.
- Candidates may only be nominated for offices published in the notice.
- The candidate winning the highest number of voters will be the nominee of the assembly for that office.
- Only assembly-goers may sign the approved signature sheets.
- All signers on a signature sheet must be registered voters in the same county.
- Once the required number of registered voters are present, they must remain in assembly until candidates have been nominated, signature sheets signed, and the convention adjourned.
Signature requirements for nomination by an assembly of electors are described in the table below.[12]
| Signature requirements for nomination by an assembly of electors in Oregon | |
|---|---|
| Office sought | Required signatures |
| United States Representative | 500 signatures obtained at the assembly |
| Governor, secretary of state, treasurer, attorney general, United States Senator | 1,000 signatures obtained at the assembly |
| State senator and state representative | 250 signatures obtained at the assembly |
Once the nomination process has been completed, the assembly is adjourned. The secretary of state collects all completed signature sheets and stamps each sheet under the last signature line signed to ensure that no additional signatures are added. Signature sheets will be then be returned to the presiding officer at the assembly, who in turn must submit the signature sheets to the appropriate county-level election official for verification. The county-level election official, upon completing the verification process, will return the forms to the presiding officer of the assembly. The candidate or presiding officer of the assembly must then submit to the Oregon Secretary of State a candidate filing form with the certificate of nomination completed by the presiding officer and secretary of the assembly and notarized, the verified signature sheets, and the proof of published notice affidavit. The Oregon Secretary of State will then determine whether the filing packet and petition are valid.[12]
For write-in candidates
Write-in candidates are not required to submit candidate filing forms in advance. In the event that a write-in candidate is nominated or elected, the election official will notify the candidate by sending a write-in candidate filing form. To accept the nomination or office, the candidate must complete, sign, and return the form to the election official.

Trifectas
A state government trifecta is a term that describes single-party government, when one political party holds the governor's office and has majorities in both chambers of the legislature in a state government. Democrats in Oregon gained a state government trifecta as a result of the 2012 elections by regaining control of the state House. The state House was split 30-30 after the 2010 elections. Democrats also held a trifecta from 2006 until 2010.

Wave election analysis
- See also: Wave elections (1918-2016)
The term wave election is frequently used to describe an election cycle in which one party makes significant electoral gains. How many seats would Republicans have had to lose for the 2018 midterm election to be considered a wave election?
Ballotpedia examined the results of the 50 election cycles that occurred between 1918 and 2016—spanning from President Woodrow Wilson's (D) second midterm in 1918 to Donald Trump's (R) first presidential election in 2016. We define wave elections as the 20 percent of elections in that period resulting in the greatest seat swings against the president's party.
Applying this definition to state legislative elections, we found that Republicans needed to lose 494 seats for 2018 to qualify as a wave election.
The chart below shows the number of seats the president's party lost in the 10 state legislative waves from 1918 to 2016. Click here to read the full report.

Competitiveness
Every year, Ballotpedia uses official candidate lists from each state to examine the competitiveness of every state legislative race in the country. Nationally, there has been a steady decline in electoral competitiveness since 2010. Most notable is that the number of districts with general election competition has dropped by more than 10 percent.
Results from 2016

Historical context
Uncontested elections: In 2014, 32.8 percent of Americans lived in states with an uncontested state senate election. Similarly, 40.4 percent of Americans lived in states with uncontested house elections. Primary elections were uncontested even more frequently, with 61 percent of people living in states with no contested primaries. Uncontested elections often occur in locations that are so politically one-sided that the result of an election would be a foregone conclusion regardless of whether it was contested or not.
Open seats: In most cases, an incumbent will run for re-election, which decreases the number of open seats available. In 2014, 83 percent of the 6,057 seats up for election saw the incumbent running for re-election. The states that impose term limits on their legislatures typically see a higher percentage of open seats in a given year because a portion of incumbents in each election are forced to leave office. Overall, the number of open seats decreased from 2012 to 2014, dropping from 21.2 percent in 2012 to 17.0 percent in 2014.
Incumbent win rates: Ballotpedia's competitiveness analysis of elections between 1972 and 2014 documented the high propensity for incumbents to win re-election in state legislative elections. In fact, since 1972, the win rate for incumbents had not dropped below 90 percent—with the exception of 1974, when 88 percent of incumbents were re-elected to their seats. Perhaps most importantly, the win rate for incumbents generally increased over time. In 2014, 96.5 percent of incumbents were able to retain their seats. Common convention holds that incumbents are able to leverage their office to maintain their seat. However, the high incumbent win rate may actually be a result of incumbents being more likely to hold seats in districts that are considered safe for their party.
Marginal primaries: Often, competitiveness is measured by examining the rate of elections that have been won by amounts that are considered marginal (5 percent or less). During the 2014 election, 90.1 percent of primary and general election races were won by margins higher than 5 percent. Interestingly, it is usually the case that only one of the two races—primary or general—will be competitive at a time. This means that if a district's general election is competitive, typically one or more of the district's primaries were won by more than 5 percent. The reverse is also true: If a district sees a competitive primary, it is unlikely that the general election for that district will be won by less than 5 percent. Primaries often see very low voter turnout in comparison to general elections. In 2014, there were only 27 million voters for state legislative primaries, but approximately 107 million voters for the state legislative general elections.
Redistricting in Oregon
- See also: Redistricting in Oregon
Because state senators in Oregon serve four-year terms, winning candidates in this election served through 2022 and played a role in Oregon's redistricting process. In Oregon, the state legislature is primarily responsible for drawing both congressional and state legislative district lines. If the legislature fails to approve a state legislative district map, the secretary of state must draw the boundaries. There is no similar backup provision for congressional redistricting.
Redistricting after the 2010 Census
Following the 2010 United States Census, Oregon neither gained nor lost congressional seats. On June 10, 2011, the state legislature approved a state legislative redistricting plan. It was signed into law on June 13, 2011. The state legislature approved a congressional redistricting plan on June 30, 2011, and it was signed into law by the governor on the same day.[19]
Pivot Counties
- See also: Pivot Counties by state
Two of 36 Oregon counties—5.6 percent—are Pivot Counties. Pivot Counties are counties that voted for Barack Obama (D) in 2008 and 2012 and for Donald Trump (R) in 2016. Altogether, the nation had 206 Pivot Counties, with most being concentrated in upper midwestern and northeastern states.
| Counties won by Trump in 2016 and Obama in 2012 and 2008 | |||||||
|---|---|---|---|---|---|---|---|
| County | Trump margin of victory in 2016 | Obama margin of victory in 2012 | Obama margin of victory in 2008 | ||||
| Columbia County, Oregon | 11.46% | 5.16% | 12.02% | ||||
| Tillamook County, Oregon | 5.58% | 4.86% | 9.89% | ||||
In the 2016 presidential election, Hillary Clinton (D) won Oregon with 50.1 percent of the vote. Donald Trump (R) received 39.1 percent. In presidential elections between 1900 and 2016, Oregon cast votes for the winning presidential candidate 73.3 percent of the time. In that same time frame, Oregon supported Republican candidates for president more often than Democratic candidates, 56.7 to 43.3 percent. The state, however, favored Democrats in every election between between 2000 and 2016.

Data on the results of the 2012 and 2016 presidential elections broken down by state legislative districts was compiled by Daily Kos.[20][21]
| In 2012, Barack Obama (D) won 19 out of 30 state Senate districts in Oregon with an average margin of victory of 26.6 points. In 2016, Hillary Clinton (D) won 20 out of 30 state Senate districts in Oregon with an average margin of victory of 26.7 points. Clinton won five districts controlled by Republicans heading into the 2018 elections. |
| In 2012, Mitt Romney (R) won 11 out of 30 state Senate districts in Oregon with an average margin of victory of 16.7 points. In 2016, Donald Trump (R) won 10 out of 30 state Senate districts in Oregon with an average margin of victory of 24.1 points. Trump won two districts controlled by Democrats heading into the 2018 elections. |

- ↑ Ballotpedia defines an incumbent as retiring if the incumbent did not file for office or filed for office but withdrew, was disqualified, or otherwise left a race in a manner other than losing the primary, primary runoff, or convention. If an incumbent runs as a write-in candidate, Ballotpedia does not consider them to be retiring. If an incumbent runs in the same chamber for a different seat, Ballotpedia does not consider them to be retiring.

- ↑ Gerald Ford's (R) first term began in August 1974 following the resignation of President Richard Nixon (R), who was first elected in 1968 and was re-elected in 1972. Because Ford only served for two full months before facing the electorate, this election is classified as Nixon's second midterm.
