The 2018 cases consisted of three seats with no Democratic candidate on the general election ballot and 38 seats without a Republican candidate. The number of seats without a Democratic candidate dropped over the course of the three election cycles; it fell from 36 in 2014 to three in 2018. In comparison, 40 U.S. House races did not have a Republican candidate in 2014 compared to 38 in 2018.

From 1920 to 2018, there were 2,434 U.S. House races without a Republican candidate in the general election compared to 707 races without a Democratic candidate. During that time span, only the following six states had a Democratic and a Republican candidate for each of their U.S. House elections every cycle: Alaska, Delaware, Idaho, Montana, New Hampshire, and Wyoming. Excluding those states, seven states (Connecticut, Kansas, Nebraska, Nevada, North Dakota, South Dakota, and Utah) had Republican candidates every cycle, and six states (Hawaii, Indiana, Maryland, New Jersey, Rhode Island, and West Virginia) had Democratic candidates every cycle.[2]

## Footnotes[edit]

1. ↑ The term major party is used in this article to refer to the Democratic Party and the Republican Party.
2. ↑ Alaska and Hawaii are the only two states that had not gained statehood by 1920. Alaska officially became a state on January 3, 1959, and Hawaii became a state on August 21, 1959. Before they became states, Alaska and Hawaii elected non-voting delegates to Congress. Alaska's first U.S. House election was in 1958, while Hawaii's first was in 1960.
3. ↑ In California and Washington state, which have top-two primary systems, a race was included if no candidate from a major party advanced to the general election.
4. ↑ Pennsylvania adopted a new congressional district map beginning in the 2018 election cycle. While district locations and numbers were changed by the new map, data on this page is listed by district number only. As a result, Pennsylvania's 18th Congressional District was listed as having no Democratic candidate in 2014 and 2016 while having no Republican candidate in 2018.
5. ↑ All eight of Alabama's congressional seats were at-large districts in the 1962 election. There was a Democratic candidate for each of these districts while there were four seats that did not have a Republican candidate. This was counted as four seats without a Republican candidate.
6. ↑ In 1952 in North Dakota, two at-large seats were on the ballot, but there was only one Democrat who filed to run. This was counted as one seat without a Democratic candidate.
7. ↑ In 1948 in North Dakota, two at-large seats were on the ballot, but there was only one Democrat who filed to run. This was counted as one seat without a Democratic candidate.
