Recent polling averages show Democratic nominee Graham Platner holding narrow leads over Republican incumbent Susan Collins in head-to-head matchups, with results ranging from 48-51% to 42-49% across surveys conducted in late May and early June 2026. Primaries held June 9 produced clear nominees on both sides after Governor Janet Mills withdrew from the Democratic contest, leaving Platner to consolidate support. Maine’s ranked-choice voting system and the state’s recent electoral trends favoring Democrats in federal races contribute to trader positioning, though Collins retains name recognition and a history of outperforming partisan expectations in past cycles. The 66.5% implied probability for a Democrat reflects this polling edge and primary clarity heading into the November general election.
