Incumbent Representative April McClain Delaney holds an 83% implied probability in the Maryland 6th District Democratic primary on June 23, ahead of former Representative David Trone at 16%, reflecting her consistent double-digit polling leads and stronger position among Democratic primary voters. Delaney benefits from her current incumbency after succeeding Trone in 2024, along with endorsements from party leaders and substantial self-funding that supports campaign visibility. Trone’s challenge centers on his prior service in the district and heavy personal loans exceeding $10 million, yet recent surveys show him trailing despite aggressive advertising and criticism of Delaney’s immigration-related votes. The race has featured increasingly pointed exchanges over campaign messaging and policy differences, with minor candidates remaining far behind in both polls and resources. The June primary date creates a short window for any late shifts in voter preferences.
