Twenty-four of 49 seats in the Nebraska State Senate were up for election in 2018. At the time of the election, 30 of the officially nonpartisan body's members were aligned with the Republican Party, 16 were aligned with the Democratic Party, one was aligned with the Libertarian Party, and one was unaligned. There was one vacancy. Following the election, 30 members of the body were aligned with the Republican Party, 18 were aligned with the Democratic Party, and one was unaligned.
Because state senators in Nebraska serve four-year terms, winning candidates in this election served through 2022 and played a role in Nebraska's redistricting process. In Nebraska, both congressional and state legislative district boundaries are drawn by the state legislature.
The Nebraska State Senate was one of 87 state legislative chambers holding elections in 2018. There are 99 chambers throughout the country.
Nebraska state senators serve staggered, four-year terms and half of the Senate is up for election every two years.

Process to become a candidate
For all candidates
According to the Nebraska Secretary of State, every prospective candidate must complete and submit a candidate filing form (which includes a candidate statement that must be signed) and provide for the payment of the filing fee. For state offices, the candidate must submit a statement of financial interests. A candidate for federal office must submit a financial statement according to Federal Election Commission instructions.[3][4]
Filing fees vary by office and are established by Chapter 32, Section 608, of the Nebraska Revised Statutes.[5][6]
Filing fees | |
---|---|
Office sought | How the fee is determined |
United States Senator or United States Representative | 1% of the office's annual salary |
Governor | 1% of the office's annual salary |
Secretary of state | 1% of the office's annual salary |
State auditor | 1% of the office's annual salary |
State treasurer | 1% of the office's annual salary |
Attorney general | 1% of the office's annual salary |
Public service commissioner | 1% of the office's annual salary |
State senator | 1% of the office's annual salary |
If the office for which the candidate is filing pays only a per diem (i.e., an allowance for expenses incurred as a result of fulfilling an office's duties) or a salary of less than $500 per year, the filing fee is waived. In addition, no filing fee is required of any candidate who completes an affidavit requesting to file in forma pauperis (i.e., a person whose "income and other resources for maintenance are found to be insufficient for meeting the cost of his or her requirements and whose cash or other available resources do not exceed the maximum available resources that an eligible individual may own").[5]
For partisan candidates
See statutes: Chapter 32, Section 610 of the Nebraska Revised Statutes
To be eligible for inclusion on a partisan primary ballot, a candidate must be a registered voter of the party, if so required. A partisan candidate must complete the aforementioned paperwork and pay the filing fees required of all candidates.[7]
For independent candidates
See statutes: Chapter 32, Section 616 of the Nebraska Revised Statutes
Any registered voter who was not a candidate in the primary election and who was not registered to vote with a party affiliation on or before March 1 in the calendar year of the general election may have his or her name placed on the general election ballot either by petition or nomination by political party convention or committee. The number of signatures required for nominating petitions varies by office (see below table for more information).[8][9]
Signature requirements | |
---|---|
Office sought | Number of signatures required |
Nonpartisan office (including state legislators) filled by registered voters of a county or political subdivision | 10% of the total number of registered voters voting for governor or president at the most recent general election; not to exceed 2,000 |

Nebraska political history
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.

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. Republicans in Nebraska held a state government trifecta for 19 years between 1992 and 2017. During the same period of time, Democrats held a trifecta for seven years.

Impact of term limits
The Nebraska State Senate has been a term-limited state Senate since Nebraska voters approved Initiative 415 (2000). Under the terms of Initiative 415, Nebraska's senators can serve no more than two consecutive four-year terms in the state Senate.
A total of 24 out of 49 seats in the Nebraska State Senate were up for election in 2018. In the 2018 elections, six senators were ineligible to run because of term limits. The following state senators were term-limited in 2018:
Nonpartisan: (6)
Of the 87 state legislative chambers that held elections in 2018, 24 of them—12 senate chambers and 12 house chambers—included incumbents who were unable to run for re-election due to term limits.[12] In the 24 chambers affected by term limits in 2018, 1,463 seats were up for election.[13] The Nevada Senate, Arkansas House, and Arkansas Senate are impacted by term limits, but no incumbents were term-limited in 2018. There are 99 chambers throughout the country.
A total of 271 state legislators—96 state senators and 175 state representatives—were ineligible to run in the 2018 elections because of term limits. This represented 4 percent of the 6,066 total seats up for election in November 2018.[14][15] Republicans had twice as many state legislators term-limited in 2018 than Democrats. A total of 86 Democrats were term-limited, while 177 Republicans were term-limited.
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
Below is Ballotpedia's 2016 competitiveness analysis. Click here to read the full study »
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 Nebraska
- See also: Redistricting in Nebraska
Because state senators in Nebraska serve four-year terms, winning candidates in the 2018 election served through 2022 and played a role in Nebraska's redistricting process—the drawing of boundary lines for congressional and state legislative districts. In Nebraska, both congressional and state legislative district boundaries are drawn by the state legislature. Prior to 2020-2022, redistricting last took place in Nebraska from 2011-2012.
State process
In Nebraska, both congressional and state legislative district boundaries are drawn by the state legislature. A simple majority is required to approve a redistricting plan, which is subject to veto by the governor.[19]
The Nebraska Constitution requires that state legislative districts "be contiguous and compact, and they keep to county boundaries 'whenever practicable.'"[19][20]
On April 8, 2011, the state legislature approved the following redistricting guidelines:[19]
- Congressional districts should be held to the same aforementioned constitutional requirements as state legislative districts.
- Both congressional and state legislative districts should be "understandable to voters, preserve the cores of prior districts, and keep to boundaries of cities and villages when feasible."
- District boundaries "should not be established with the intention of favoring a political party, other group or any person."
The legislature is entitled to amend these guidelines at its discretion.[19]
Pivot Counties
- See also: Pivot Counties by state
One of 93 Nebraska counties—1.08 percent—is a Pivot County. 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.

Thurston County, Nebraska | 5.94% | 13.91% | 6.96% |
In the 2016 presidential election, Donald Trump (R) won Nebraska with 58.7 percent of the vote. Hillary Clinton (D) received 33.7 percent. In presidential elections between 1868 and 2016, Nebraska voted Republican 82 percent of the time and Democratic 18 percent of the time. In the five presidential elections between 2000 and 2016, Nebraska voted Republican all five times.[21]
Presidential results by legislative district
The following table details results of the 2012 and 2016 presidential elections by state Senate districts in Nebraska. Click [show] to expand the table. The "Obama," "Romney," "Clinton," and "Trump" columns describe the percent of the vote each presidential candidate received in the district. The "2012 Margin" and "2016 Margin" columns describe the margin of victory between the two presidential candidates in those years. The "Party Control" column notes which party held that seat heading into the 2018 general election. Data on the results of the 2012 and 2016 presidential elections broken down by state legislative districts was compiled by Daily Kos.[22][23]
In 2012, Barack Obama (D) won 10 out of 49 state Senate districts in Nebraska with an average margin of victory of 26.2 points. In 2016, Hillary Clinton (D) won 12 out of 49 state Senate districts in Nebraska with an average margin of victory of 22.8 points. Clinton won one district controlled by a Republican heading into the 2018 elections. |
In 2012, Mitt Romney (R) won 39 out of 49 state Senate districts in Nebraska with an average margin of victory of 31.1 points. In 2016, Donald Trump (R) won 37 out of 49 state Senate districts in Nebraska with an average margin of victory of 38.3 points. Trump won five districts controlled by Democrats heading into the 2018 elections. |
