In 2022, there were 35 U.S. House races where only one of the two major parties were on the ballot. 23 of these are held by Republicans, 12 by Democrats. By our count, there were 27 in 2020, and 42 in 2018.
In this article, we'll update the list for 2024 as each state's primary takes place.
Totally Unopposed
There are 16 incumbents - 13 Republicans and three Democrats - that have the ballot all to themselves. Their only opposition would be via write-in, where allowed.
In 2020, this number was 11, split more evenly with six Republicans and five Democrats.

1Not a perfect fit for the list, as there is a second Republican on the ballot in this all-party primary. Should Graves fail to get a majority of the vote, there will be a top-two runoff. In that scenario, if the other Republican also advances, this election will move to the 'Same Party Opposition' list.
Same Party Opposition
California and Washington hold top-two primaries, where all candidates, regardless of party, appear on a single ballot. The two highest finishers go on to the general election. Six districts - all in California - advanced two Democrats.
In 2020, there were eight such districts, seven in California and one in Washington.
