2018 elections
Choose a chamber below:

Republicans expanded their majority in the 2018 elections for Tennessee State Senate, since, after the election, they controlled 28 seats to Democrats' five. Eighteen of 33 Senate seats were up for election. At the time of the election, Republicans held 26 seats to Democrats' four, with three vacancies.

The Republican Party maintained its trifecta in Tennessee in 2018 by holding its majorities in the state Senate and House and by retaining the governorship.

Because state senators in Tennessee serve four-year terms, winning candidates in the regular election served through 2022 and played a role in Tennessee's redistricting process. Congressional and state legislative district boundaries are drawn by the state legislature. Read more below.

The Tennessee State Senate was one of 87 state legislative chambers with elections in 2018. There are 99 chambers throughout the country.

Tennessee state senators serve staggered, four-year terms and half of the Senate is up for election every two years.

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 Tennessee gained a state government trifecta as a result of the 2010 elections by taking control of the governorship.

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.

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.

F5 Pop. % with uncontested state legislative races.png

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 Tennessee

See also: Redistricting in Tennessee

Because state senators in Tennessee serve four-year terms, winning candidates in this election served through 2022 and played a role in Tennessee's redistricting process. In Tennessee, congressional and state legislative district boundaries are drawn by the state legislature.

State legislature districts in the 2010-2012 redistricting process

On January 13, 2012, the state legislature approved a state House redistricting plan, which was signed into law on January 26, 2012. New state Senate lines were adopted on January 19, 2012, and signed into law on February 9, 2012.[18]

Pivot Counties

See also: Pivot Counties by state

One of 95 Tennessee counties—1 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.

County Trump margin of victory in 2016 Obama margin of victory in 2012 Obama margin of victory in 2008
Hardeman County, Tennessee 7.92% 5.91% 6.18%

In the 2016 presidential election, Donald Trump (R) won Tennessee with 60.7 percent of the vote. Hillary Clinton (D) received 34.7 percent. In presidential elections between 1900 and 2016, Tennessee cast votes for the winning presidential candidate 76.7 percent of the time. In that same time frame, Tennessee supported Democratic candidates for president and Republican candidates equally. The state, however, favored Republicans in every presidential election between 2000 and 2016.

Presidential results by legislative district

The following table details results of the 2012 and 2016 presidential elections by state Senate districts in Tennessee. 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.[19][20]

In 2012, Barack Obama (D) won 5 out of 33 state Senate districts in Tennessee with an average margin of victory of 59.3 points. In 2016, Hillary Clinton (D) won 6 out of 33 state Senate districts in Tennessee with an average margin of victory of 50 points. Clinton won one district controlled by a Republican heading into the 2018 elections.
In 2012, Mitt Romney (R) won 28 out of 33 state Senate districts in Tennessee with an average margin of victory of 33.8 points. In 2016, Donald Trump (R) won 27 out of 33 state Senate districts in Tennessee with an average margin of victory of 40.8 points.
