Heading into the election, the incumbent was Diana DeGette (Democrat), who was first elected in 1996.
A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election.
Colorado utilizes a semi-closed primary system. According to Section 1-7-201 of the Colorado Revised Statutes, "An eligible unaffiliated elector, including a preregistrant who is eligible under section 1-2-101 (2)(c), is entitled to vote in the primary election of a major political party without affiliating with that political party."[2][3]

- See also: FiveThirtyEight's elasticity scores
The 2017 Cook Partisan Voter Index for this district was D+21, meaning that in the previous two presidential elections, this district's results were 21 percentage points more Democratic than the national average. This made Colorado's 1st Congressional District the 59th most Democratic nationally.[4]
FiveThirtyEight's September 2018 elasticity score for states and congressional districts measured "how sensitive it is to changes in the national political environment." This district's elasticity score was 0.97. This means that for every 1 point the national political mood moved toward a party, the district was expected to move 0.97 points toward that party.[5]

General election race ratings
- See also: Race rating definitions and methods
Ballotpedia provides race ratings from four outlets: The Cook Political Report, Inside Elections, Sabato's Crystal Ball, and DDHQ/The Hill. Each race rating indicates if one party is perceived to have an advantage in the race and, if so, the degree of advantage:
- Safe and Solid ratings indicate that one party has a clear edge and the race is not competitive.
- Likely ratings indicate that one party has a clear edge, but an upset is possible.
- Lean ratings indicate that one party has a small edge, but the race is competitive.[8]
- Toss-up ratings indicate that neither party has an advantage.
Race ratings are informed by a number of factors, including polling, candidate quality, and election result history in the race's district or state.[9][10][11]
