Post-filing deadline analysis
The following analysis covers all state legislative districts up for election in Delaware in 2024. Information below was calculated on July 24, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.
Delaware had 13 contested state legislative primaries this year, one less than in 2022 when 14 state legislative primaries were contested.
Of the 13 contested primaries, 10 were for Democrats and three were for Republicans. For Democrats, this was one less than in 2022 when there were 11 Democratic primaries. The three Republican primaries are the same number as in 2022.
Seven incumbents faced primary challenges, representing 15.2% of all 46 incumbents who ran for re-election. This was nearly equivalent to the average number (7.29) and percentage (14.6%) of contested incumbents from 2010-2022. The average number of incumbents running across all state legislative elections from 2010-2022 was 48.86.
Of the 7 incumbents in contested primaries, five were Democrats and two were Republicans.
Overall, 81 major party candidates—52 Democrats and 32 Republicans—filed to run. All 41 House seats and 10 of 21 Senate seats were up for election.
Five of those seats (8.1%) were open, meaning no incumbents filed, and newcomers won election to those seats. This was slightly below 5.7 (9.2%), the average number of incumbents who retired each election year from 2010-2022.
Delaware had a Democratic trifecta since the party won control of the House in 2008. Democrats had a 26-15 majority in the House and a 15-6 majority in the Senate. As of July 24, 2024, there were 23 Republican trifectas, 17 Democratic trifectas, and 10 divided governments where neither party held trifecta control.

Footnotes
- ↑ Ballotpedia defines an incumbent as retiring if the incumbent did not file for office or filed for office but withdrew, was disqualified, or otherwise left a race in a manner other than losing the primary, primary runoff, or convention. If an incumbent runs as a write-in candidate, Ballotpedia does not consider them to be retiring. If an incumbent runs in the same chamber for a different seat, Ballotpedia does not consider them to be retiring.

If the incumbent withdrew from or did not participate in the primary but later chose to seek re-election to his or her seat as a third party or independent candidate, the seat would not be counted as open. If the incumbent retired or ran for a different seat in the same chamber, his or her original seat would be counted as open unless another incumbent from the same chamber filed to run for that seat, in which case it would not be counted as open due to the presence of an incumbent.
