Maine’s 2026 Senate race features longtime Republican incumbent Susan Collins seeking a sixth term against Democratic nominee Graham Platner, an oyster farmer and veteran who secured the nomination with 72% in the June 9 primary after Governor Janet Mills withdrew. Recent polls conducted in early to mid-June show a close contest, with Platner holding narrow leads or ties in most surveys amid Maine’s Democratic presidential voting pattern. Traders have priced the Democratic outcome at 66.5% versus 34.5% for the Republican, reflecting the challenger’s post-primary consolidation and the state’s underlying partisan lean, though the race remains sensitive to turnout among independents and cross-party support for the moderate incumbent ahead of the November general election.
