Because state senators in Ohio serve four-year terms, winning candidates in this election served through 2022 and played a role inOhio's redistricting process. Congressional district lines in Ohio are drawn by the state legislature. If the legislature is unable to approve a congressional redistricting plan, a backup commission must draw new lines.

The Ohio State Senate was one of 87 state legislative chambers with elections in2018. There are 99 chambers throughout the country.

Impact of term limits

See also:Impact of term limits on state senate elections in 2018 andImpact of term limits on state legislative elections in 2018

TheOhio State Senate has been a term-limited state Senate since Ohio voters approvedBallot Issue 4, aninitiated constitutional amendment, in1992. This amendment became part ofSection 2 of Article II of theOhio Constitution and limits the amount of time that anOhio state senator can stay in office to two four-year terms, saying, "No person shall hold the office of State Senator for a period longer than two successive terms of four years." Senators can run for office again after being out-of-office for at least a four-year period.

A total of 17 out of 33 seats in theOhio State Senate were up for election in 2018. In the 2018 elections, ten senators were ineligible to run because of term limits. The following state senators were term-limited in 2018:

Democratic: (4)

Republicans (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 toterm limits.[10] In the 24 chambers affected by term limits in 2018, 1,463 seats were up for election.[11] 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.[12][13] 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 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.

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'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.

In the 2016 presidential election,Donald Trump (R) won Ohio with 51.7 percent of the vote.Hillary Clinton (D) received 43.6 percent. In presidential elections between 1900 and 2016, Ohio cast votes for the winning presidential candidate 93.3 percent of the time (28 out of 30 elections), more than any other state in the country. In that same time frame, Ohio supported Republican candidates for president more often than Democratic candidates, 60 to 40 percent. Between 2000 and 2016, Ohio voted for the winning presidential candidate in every election.

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.

  16. 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.
