Manchin Joins Collins’s Maine Bid
Coverage from OddsShopper, BizPac Review, and others
Former Senator Joe Manchin, now an independent, endorsed Republican Senator Susan Collins and plans to campaign for her in Maine’s 2026 Senate contest.
Collins faces Democrat Troy Jackson after Graham Platner withdrew, while available polling places the candidates within the margin of error. Manchin’s support gives Collins a prominent cross-party surrogate as Democrats target the seat in their effort to regain Senate control.
If you read one thing

The evidence
It provides validated polling and campaign evidence about abortion rights as a substantive contrast between Jackson and Collins.
A persistently narrow race
Troy Jackson holds a small polling advantage over Susan Collins, including a 48%–45% CNN/SSRS result within the margin of error. Election models favor Collins while betting indicators favor Jackson, leaving the outcome unsettled.
Collins is reinforcing a cross-party appeal
Joe Manchin’s endorsement and planned campaigning give Collins a prominent independent-oriented surrogate and reinforce her bipartisan positioning. That asset is being deployed amid weakened favorability and Democratic efforts to associate her with national Republican politics.
Jackson has consolidated the Democratic challenge
Troy Jackson is the settled Democratic nominee after Graham Platner’s withdrawal and backing from other contenders. The transition preserved a viable challenge to Collins and left the general-election contest competitive.
The seat carries national control-of-Senate stakes
Maine remains a major Democratic target because the Collins–Jackson outcome could affect control of a narrowly divided Senate. Collins’s status as New England’s only Republican senator adds national visibility to the contest.
46% percent
women surveyed who supported Susan Collins
“Women are a key voting bloc in Maine. In the previous election, Collins only narrowly outperformed Democrat Sara Gideon among women. A Fox News poll released earlier this month found that 50% of women surveyed supported Jackson, compared with 46% for Collins.”
45% percent
support for Susan Collins

“Every independent poll since Jackson became the nominee has shown him with a small lead over Collins. A recent CNN/SSRS survey put Jackson ahead 48% to 45%, within the margin of error.”
51% percent
voters viewing Susan Collins unfavorably
“Manchin’s endorsement reinforces that image as Collins’s favorability has weakened. Recent polling shows Collins underwater by 10 points, with 51% viewing her unfavorably, and his support could appeal to moderate and independent voters.”
The new article reiterates that Joe Manchin’s endorsement reinforces Susan Collins’s bipartisan profile, without adding a material development to the contest.
