Democrats gained a majority in the 2018 elections for theNew Hampshire State Senate, winning14 seats toRepublicans'10. All24 Senate seats were up for election. At the time of the election, Republicans held14 seats to Democrats'10.

Ballotpedia identified eight of the races as battlegrounds, includingsix Republican-held districts andtwo Democratic-held districts. Democrats and Republicans each wonfour battleground races, with Democrats winning in three Republican-held districts and Republicans winning in one Democratic-held district.

Heading into the election, New Hampshire had been aRepublican trifecta since 2017 after Gov.Chris Sununu (R) was elected. The state Senate and the state House were already controlled by Republicans prior to the 2016 elections.

To retake control of the chamber in 2018, Democrats needed to gain three seats. Republicans needed to gain two seats to gain a veto-proof majority in 2018. A two-thirds majority—16 seats in the state Senate—is required to override a gubernatorial veto.

The New Hampshire State Senate was one of 87 state legislative chambers with elections in2018. There are 99 chambers throughout the country. The New Hampshire State Senate was also one of 22 state legislative battleground chambers identified by Ballotpedia in the 2018 elections.Read more below.

2018 battleground chamber

See also:State legislative battleground chambers, 2018

Ballotpedia identified the New Hampshire State Senate as one of 22 battleground chambers in 2018. These were chambers that we anticipated to be, overall, more competitive than other chambers and had the potential to see significant shifts in party control.

The chamber was selected because it met the following conditions:

  • Competitive seats: In 2016, six Republican seats had a margin of victory that was less than 10 percent. Two Democratic seats had a margin of victory that was less than 10 percent.See the 2018 races to watch here.
  • Recent party control switches: The chamber flipped from Democratic to Republican control in 2010.

Ballotpedia identifiedeight battleground races in the New Hampshire State Senate 2018 elections:two Democratic seats andsix Republican seats. Based on analysis of these districts' electoral histories, these races had the potential to be more competitive than other races and could possibly have led to shifts in a chamber's partisan balance.

To determine state legislative battleground races in 2018, Ballotpedia looked for races that fit one or more of thefour factors listed below:

  1. If the incumbent won less than 55 percent of the vote in the most recent election prior to 2018
  2. If the presidential candidate opposite of the incumbent's party won the district in the 2016 elections and the incumbent’s margin of victory in the previous election was 10 percentage points or less
  3. If the presidential candidate opposite of the incumbent's party won the district in the 2016 elections and the incumbent did not file to run for re-election
  4. If the presidential candidate opposite of the incumbent's party won the district in the 2016 elections by 20 points or more

Other factors could also cause a race to be classified as a battleground. For example, Ballotpedia may have considered an election to be a battleground race if an outside group or a national or state party announced that they were targeting a specific seat in order to flip it. We may have also determined a race to be a battleground if it received an unusual amount of media attention. Two additional factors were open seats and districts impacted by redistricting.

Trifectas

Astate 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 New Hampshire held astate government trifecta for four years between 1992 and 2017. During that same period of time, Republicans held a trifecta for eight years.

In elections between the 1990s and 2016, New Hampshire leaned Republican at the state legislative level but leaned Democratic at the statewide and presidential levels. Between 1992 and 2017, Republicans controlled the Senate for 20 years, while Democrats held the chamber for five years. In 2011, Republicans retook the state Senate, after previously holding the chamber from 1992 to 1998 and 2001 to 2006. Similar to the Senate, Republicans held the state House for 20 years between 1992 and 2017. Democrats only held the chamber for six years throughout that same period of time. During the 2006, 2010, and 2014 elections, the state House went through massive partisan swings. Democrats overcame a 98-seat Republican majority in the 2006 elections before Republicans rebounded in the 2010 elections. Republicans overcame a 40-seat majority in 2014 to retake control of the chamber.

Democrats controlled the governor's office for 18 years between 1992 and 2016. RepublicanChris Sununu was elected to the office in 2016. Prior to Sununu's election in 2016, Republicans had only held the governor's office for seven years between 1992 and 2016. Sununu's victory made the state aRepublican trifecta, meaning Republicans controlled both chambers of the legislature and the governor's mansion.

Wave election analysis

See also:Wave elections (1918-2016)

The termwave election is frequently used to describe an election cycle in which one party makessignificant 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 PresidentWoodrow Wilson's (D) second midterm in 1918 toDonald 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 tostate legislative elections, we found that Republicans needed to lose494 seats for 2018 to qualify as awave 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.

Historical context

See also:Competitiveness in State Legislative Elections: 1972-2014

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'scompetitiveness 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.

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.

  7. 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.
