Incumbent April McClain Delaney maintains a strong polling lead over former Representative David Trone in the June 23 Democratic primary for Maryland’s 6th Congressional District, reflecting her advantages as sitting representative and consistent double-digit margins in recent surveys. Trone’s heavy self-funding and combative messaging on immigration enforcement have not closed the gap, as voters appear to favor Delaney’s record and endorsements from state leaders. The race has grown more negative in recent weeks, with disputes over campaign rhetoric and past congressional votes, yet minor candidates remain far behind in both polling and fundraising. Traders view Delaney’s position as dominant ahead of the primary, while noting the narrow window for any late shifts.
