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. Delaware utilizes a closed primary process, in which the selection of a party's candidates in an election is limited to registered party members.

For information about which offices are nominated via primary election, see this article.

This page focuses on Delaware's Republican primary for the U.S. House. For more in-depth information on the state's Democratic primary and the general election, see the following pages:

Post-filing deadline analysis

The following analysis covers all U.S. House districts up for election in Delaware in 2024. Information below was calculated on July 18, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.

Five candidates ran for Delaware's At-Large Congressional District, including three Democrats and two Republicans. Two candidates ran in 2022, three candidates ran in 2020, and three ran in 2018.

The five candidates who ran in Delaware in 2024 was the highest number of candidates since 2016, when seven candidates ran.

Delaware’s At-Large Congressional District was open in 2024 because incumbent Rep. Lisa Blunt Rochester (D) ran for the U.S. Senate. The only other year that the district was open in the last 10 years was 2016.

The Democratic and Republican primaries were both contested in 2024. This was the only year in the last 10 years in which both primaries were contested.

Candidates filed to run in the Republican and Democratic primaries, meaning the seat is not guaranteed to either party.
