Kiggans, also a former Naval officer, is unopposed in the Republican primary. A contested primary is also underway in the neighboring 1st Congressional District, where seven Democratic hopefuls are running to unseat Republican U.S. Rep. The Democratic primary in the 5th Congressional District also features a comeback attempt by a former member of Congress. Advance voting tends to make up a larger share of the vote in Democratic primaries than in Republican primaries. In 2024, about 55% of the vote in the 1st District Democratic primary and about 47% of the 2nd District Democratic primary vote were mail or early in-person votes.
