2018 elections
Choose a chamber below:

Republicans maintained their majority in the 2018 elections for the Iowa House of Representatives despite losing seats, winning 54 seats to Democrats' 46. All 100 House seats were up for election. At the time of the election, Republicans held 58 seats to Democrats' 41, with one vacancy.

Ballotpedia identified 15 of the races as battlegrounds, including nine Republican-held districts and six Democratic-held districts. Of the 15 battleground seats, Republicans won seven, including two in Democratic-held districts, and Democrats won eight battleground races, including four in Republican-held districts.

Heading into the election, Iowa had been a Republican trifecta since 2016 when Republicans took control of the Iowa State Senate. Republicans took control of the state House and the governorship in the 2010 elections. The last Democratic trifecta in Iowa formed after the 2006 elections and lasted until 2010. Had the Democratic Party taken the chamber, it would have broken the Republican trifecta.

The Iowa House of Representatives was one of 87 state legislative chambers holding elections in 2018. There are 99 chambers throughout the country. The Iowa House of Representatives was one of 22 state legislative battleground chambers identified by Ballotpedia in the 2018 elections. Read more below.

Iowa state representatives serve two-year terms, with all seats up for election every two years.

2018 battleground chamber[edit]

See also: State legislative battleground chambers, 2018

Ballotpedia identified the Iowa House of Representatives 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, five seats won by Democrats had a margin of victory that was less than 10 percent. Seven seats won by Republicans had a margin of victory that was less than 10 percent. See the 2018 battleground races.

Retirements: Seventeen state House members, 13 Republicans and four Democrats, did not seek re-election in 2018.

Competitive statewide race: Gov. Kim Reynolds (R), who assumed the governorship in 2017 after incumbent Terry Branstad (R) resigned, sought her first elected term in 2018. Electoral ratings organizations expected the race to be competitive between the two parties. The governor's office was previously controlled by a Democrat from 1999 to 2010. Read more about the 2018 gubernatorial race here.

2016 presidential election results: Donald Trump (R) won 10 districts that elected Democrats to the state House. Hillary Clinton (D) won four districts that elected Republicans to the state House.

Recent party control switches: The chamber flipped from Republican to Democratic control in 2006 and then came back under Republican control in 2010.

Battleground races[edit]

Ballotpedia identified 15 battleground races in the Iowa House of Representatives 2018 elections: six Democratic seats and nine 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 the four factors listed below:

If the incumbent won less than 55 percent of the vote in the most recent election prior to 2018
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
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
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[edit]

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 Iowa gained a state government trifecta as a result of the 2016 elections. Democrats had trifectas in the state from 2007 to 2010. Republicans previously held a Republican trifecta from 1997 to 1998.

Iowa ballot measures[edit]

Iowa's process for putting legislatively referred constitutional amendments before voters was designed to allow legislative elections to determine the fate of proposed constitutional amendments approved in the previous session. To put a legislatively referred constitutional amendment before voters, a simple majority vote is required in both the Iowa State Senate and the Iowa House of Representatives in two legislative sessions with an election for state legislators in between. Every two years, half of the state senators and all of the members of the state House are up for election.

During the 2017-2018 legislative session in Iowa, two proposed constitutional amendments were approved: the Iowa Gubernatorial Succession Amendment and the Iowa Right to Firearms Amendment. Both amendments were approved largely along party lines. The gubernatorial succession amendment—which was designed to allow the governor to appoint a replacement lieutenant governor if there is a vacancy—was approved by all 26 voting Republicans in the Senate and all 57 voting Republicans in the House. Voting Democrats were split 10-10 in the Senate, while all 40 voting Democrats voted against the amendment in the House. The amendment to add a right to own and bear firearms to the state constitution was approved by all Republicans in the Senate and by 54 of 56 voting Republicans in the House. In the Senate, 15 of 20 voting Democrats voted against it, and, in the House, all 40 voting Democrats voted against it. The one Independent state senator voted in favor of both amendments.

Iowa became a Republican trifecta in 2016 when Republicans flipped the state Senate. Republicans took control of the governor's office and the state House in the 2010 elections. Entering the November 2018 election, Iowa is one of 26 Republican state government trifectas. To retake control of the state Senate in 2018, Democrats needed to flip five seats. In the state House, Republicans had a 59-41 majority. In the 2018 elections, Republicans maintained their Trifecta control of the state.

After the 2018 elections, legislators were set to consider both amendments in the 2019-2020 legislative session. Ultimately, however, the secretary of state did not publish the approval of the amendments according to state law requirements. This invalidated the approval in the 2017-2018 session and required the two-session process to be started over for these two amendments.

Wave election analysis[edit]

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.

Candidate and office information[edit]

Process to become a candidate[edit]

See also: Ballot access requirements for political candidates in Iowa

See statutes: Title II of the Iowa Code

There are four ways in which a candidate can gain access to the general election ballot: by primary election, by political party convention, by Non-party Political Organization (NPPO) convention, or by petition. These are detailed below.

Iowa allows any registered voter to challenge a candidate's nominating petition, as long as the challenge is made in writing and within 74 days of the corresponding election.^[11]^[12]

By primary election[edit]

A candidate seeking the nomination of a state-recognized political party in a primary election must be a member of that party. Non-party Political Organizations (NPPOs) are not permitted to participate in primary elections. A primary election candidate must file an affidavit of candidacy and nomination petition with the Iowa Secretary of State during the primary election filing period, which begins 99 days before the primary and ends at 5 p.m. on the 81st day before the primary. The affidavit of candidacy and the nomination petition must be filed simultaneously.^[13]^[14]

For the number of signatures required for nomination petitions, see the table below.

Formulas for determining signature requirements for political party candidates in primary elections
Office sought	Number of signatures needed
Governor or United States Senator	"At least 1 percent of the voters of the candidate's party, in each of at least 10 counties in the state, and in the aggregate not less than 0.5 perfect of the total vote of the candidate's party in the state, as shown in the last general election"^[15]
State executive office (other than governor)	1,000, including 50 from each of at least 10 counties in the state^[15]
United States Representative	"At least 2 percent of the voters of the candidate's party, as shown by the last general election, in each of at least one-half of the counties of the district, and in the aggregate not less than 1 percent of the total vote of the candidate's party in such district, as shown by the last general election"^[15]
State Senator	100 from the senatorial district^[15]
State Representative	50 from the representative district^[15]

By political party convention[edit]

If a political party fails to nominate a candidate at the primary election, the party may hold a convention after the primary to nominate a candidate. That candidate must then file a political party convention certificate and an affidavit of candidacy. The deadline to file the convention certificate and affidavit of candidacy is the same as the general election filing deadline. However, a political party convention candidate may file his or her documents before the filing period begins for general election candidates.^[16]

By Non-party Political Organization (NPPO) convention[edit]

Non-party Political Organizations (NPPOs) are permitted to hold conventions to nominate their candidates. However, in order to qualify their nominations, NPPOs must meet the following requirements:^[16]^[17] ^[18]

To nominate a candidate to a state executive office or the United States Senate, 500 eligible electors, meaning people who meet all the requirements to register to vote, must attend the convention, and 25 counties must be represented by at least one eligible elector each.
To nominate a candidate to the United States House of Representatives, 200 eligible electors who are residents of the congressional district the candidate seeks to represent must attend, including one eligible elector from at least half of the counties in the district.
To nominate a candidate to the Iowa State Senate, 50 eligible electors who are residents of the senatorial district must attend, including one eligible elector from one-half of the precincts in the senatorial district.
To nominate a candidate to the Iowa House of Representatives, 25 eligible electors who are residents of the representative district must attend, including one eligible elector from one-half of the precincts in the representative district.
A convention may be held at any time as long as it is before the general election filing deadline.^[19]
After the convention, the NPPO must provide a list of those who attended the convention, including their addresses, to the Iowa Secretary of State, along with a convention certificate and an affidavit of candidacy for the candidate nominated. These documents must be filed together during the general election filing period, which begins 99 days before the general election and ends at 5 p.m. 81 days before the general election.^[19]^[16]^[12]

By petition[edit]

A candidate who is not affiliated with any political party or NPPO can be nominated by petition. A NPPO candidate can gain ballot access in this manner if the NPPO cannot meet the convention attendance requirements described above. A petition candidates must file an affidavit of candidacy and nomination petition with the Iowa Secretary of State. These forms must be filed together by 5 p.m. 81 days before the general election.^[12]^[17]

The table below details the signature requirements necessary for obtaining ballot access by petition.

Formulas for determining signature requirements for NPPO candidates
Office sought	Number of signatures needed
United States Senator or governor	3,500 eligible electors, including at least 100 from at least 19 counties^[16]^[17]
Otherwise statewide executive offices	2,500 eligible electors, including at least 77 from at least 18 counties^[16]^[17]
United States Representative	1,726 eligible electors who are residents of the congressional district, including at least 47 eligible electors each from at least one-half of the counties in the congressional district^[16]^[17]

Qualifications[edit]

Competitiveness[edit]

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[edit]

Below is Ballotpedia's 2016 competitiveness analysis. Click here to read the full study »

Historical context[edit]

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'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.

Pivot Counties[edit]

See also: Pivot Counties by state

Thirty-one of 99 Iowa counties—31 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.

Footnotes[edit]

↑ ^1.0 ^1.1 Excludes unopposed 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.
↑ District 43 Rep. Chris Hagenow (R) did not file for re-election to the 43rd District, but he did file for state House District 19. Ballotpedia considers him an incumbent because he saught a different seat in the same chamber, so Hagenow is not listed below.
↑ This district was marked as a battleground because the incumbent did not file for re-election and the seat swung from R+14.1 in the 2012 presidential election to R+2.8 in the 2016 presidential election.
↑ This district was marked as a battleground because the incumbent did not file for re-election and the seat swung from D+5.8 in the 2012 presidential election to R+16.6 in the 2016 presidential election.
↑ This district was marked as a battleground because the incumbent did not file for re-election and the seat swung from R+0 in the 2012 presidential election to R+26 in the 2016 presidential election.
↑ This margin of victory is from a 2017 special election for the seat.
↑ The number of state legislative seats available for analysis varied, with as many as 7,795 and as few as 6,835.
↑ Lyndon Johnson's (D) first term began in November 1963 after the death of President John F. Kennedy (D), who was first elected in 1960. Before Johnson had his first midterm in 1966, he was re-elected president in 1964.
↑ 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.
