Susan Collins Gets Big Update From Maine Poll: Inside the Numbers, the Race, and the Battle for the Senate
The political landscape in Pine Tree State just received a massive jolt. A brand-new wave of polling out of Maine reveals that five-term Republican Senator Susan Collins is entering the final stretch of her 2026 re-election campaign facing some of the toughest headwinds of her thirty-year career in the United States Senate.
Long regarded as one of the most durable political figures in modern New England history, Collins—the sole remaining Republican senator representing a state carried by Democrats in recent presidential elections—finds herself in a high-stakes, toss-up race that could ultimately decide the balance of power in the U.S. Senate.
With less than three months until Election Day, the latest polling data paints a vivid picture of a deeply polarized electorate, shifting candidate dynamics, and a electorate wrestling with national political debates over the judiciary, reproductive rights, and economic pressure.
Here is an in-depth breakdown of the latest polling numbers, the crucial political factors driving the race, and what this big update means for Susan Collins and the battle for the Senate majority.
Act I: The Big Numbers — Inside the Latest Maine Polling Data
The newest survey from Hart Research—commissioned by the Senate Majority PAC—alongside recent data from the University of New Hampshire and Pan Atlantic Research, indicates that the 2026 Maine Senate race is locked in a tight, competitive contest.
In head-to-head matchup testing, Democratic nominee Troy Jackson, the former Maine State Senate President, holds a narrow lead over incumbent Senator Susan Collins:
+-----------------------------------------------------------------------+
| MAINE U.S. SENATE HEAD-TO-HEAD |
+-----------------------------------------------------------------------+
| CANDIDATE | PARTY | SUPPORT (%) |
+-----------------------------------+-------------+---------------------+
| Troy Jackson | Democrat | 49% |
| Susan Collins (Incumbent) | Republican | 45% |
| Undecided / Other | -- | 6% |
+-----------------------------------+-------------+---------------------+
*Margin of Error: ±3.5% (Hart Research / August 2026)
Beyond the top-line ballot test, the underlying metrics reveal deeper structural shifts across the state's electorate.
Approval and Favorability Metrics
For decades, Susan Collins enjoyed comfortable approval ratings, often buoyed by strong support among independent and moderate voters across Maine. However, the latest survey numbers show her job performance ratings underwater:
Job Disapproval: 52% of respondents disapprove of Collins' performance in the Senate, compared to 46% who approve.
Other statewide polls, such as Pan Atlantic Research and Morning Consult, have placed her approval rating even lower, reflecting sustained post-2022 headwinds. Favorability Gap: Collins’ net favorability sits at -4 (48% favorable / 52% unfavorable).
Challenger Favorability: By contrast, Democratic challenger Troy Jackson enters the general election sprint with a net positive favorability rating of +12 (47% favorable / 35% unfavorable).
+---------------------------------------------------------------------------+
| CANDIDATE FAVORABILITY RATINGS |
+---------------------------------------------------------------------------+
| CANDIDATE | FAVORABLE | UNFAVORABLE | NET FAVORABILITY |
+----------------------+---------------+---------------+--------------------+
| Susan Collins (R) | 48% | 52% | -4 |
| Troy Jackson (D) | 47% | 35% | +12 |
+----------------------+---------------+---------------+--------------------+
Generic Ballot & National Environment
The poll also highlights broader state sentiment regarding national governance:
Senate Majority Preference: By an 18-point margin (54% to 36%), Maine voters surveyed expressed a preference for a Democratic majority in the U.S. Senate to act as a check on federal executive power.
Presidential Drag: Disapproval of President Donald Trump in Maine stands at 61%, creating an undeniable top-of-ticket drag for down-ballot Republicans in a state that voted Democratic in the 2024 presidential contest.

Act II: The Democratic Shakeup — From Platner to Troy Jackson
To understand why the 2026 Maine Senate race has suddenly reached a fever pitch, one must look at the wild sequence of events that reshaped the Democratic ticket over the mid-summer months.
THE 2026 DEMOCRATIC TICKET TIMELINE
[June 9, 2026] Graham Platner wins Democratic Primary (72.1% of vote)
|
v
[July 6, 2026] Allegations against Platner emerge; party calls for exit
|
v
[July 10, 2026] Platner officially withdraws from the general election
|
v
[July 25, 2026] Nominating Convention selects Troy Jackson as Nominee
The June Primary and July Crisis
In the June 9 Democratic primary, progressive organizer Graham Platner delivered a stunning upset victory over establishment figures, including Governor Janet Mills, securing over 72% of the primary vote.
However, in early July, severe personal allegations and campaign controversies surfaced regarding Platner, prompting top state and national Democrats to call for his departure.
Enter Troy Jackson
On July 25, at an emergency state nominating convention, delegates overwhelmingly selected Troy Jackson—a former state Senate President, logger, and seasoned union advocate from Allagash in Aroostook County—to take over the nomination.
Jackson’s entry dramatically altered the race's chemistry:
Working-Class Authenticity: As a former logger and long-time labor leader, Jackson possesses deep roots among blue-collar Mainers in the state’s rural 2nd Congressional District, where national Democrats have often struggled.
GovernmentLegislative Experience: Serving as President of the Maine State Senate gave Jackson a proven track record of passing state legislation on healthcare expansion, prescription drug pricing, and labor protections.
Consolidation: Unlike a protracted primary fight, Jackson’s swift selection united the party’s moderate and progressive wings almost overnight.
Act III: The Shadow of 2020 — Can Collins Defy the Polling Gravity Again?
While national Democrats view the new polling numbers as a sign of momentum, the Collins campaign and veteran Maine political observers urge caution before drawing definitive conclusions.
There is an obvious historical reason for this skepticism: the 2020 election.
+---------------------------------------------------------------------------+
| 2020 VS. 2026: POLLS VS. ACTUAL OUTCOME |
+---------------------------------------------------------------------------+
| ELECTION YEAR | LATE-SUMMER POLL AVERAGE | FINAL ELECTION RESULT |
+-----------------+------------------------------+--------------------------+
| 2020 | Sara Gideon (D) +4 to +6 | Susan Collins (R) +8.6 |
| 2026 (Current) | Troy Jackson (D) +3 to +4 | TBD (Nov 3, 2026) |
+-----------------+------------------------------+--------------------------+
The 2020 Polling Mismatch
In the summer of 2020, nearly every published poll showed Democratic nominee Sara Gideon leading Susan Collins by 3 to 7 percentage points.
The Collins Campaign Response
Predictably, the Collins campaign dismissed the latest Hart Research survey, framing it as a partisan product designed to drum up donor excitement.
Campaign spokesperson Shawn Roderick noted that outside groups "spent tens of millions running attack ads" in previous cycles, only for Mainers to re-elect Collins due to her constituent service and unmatched seniority.
"Every single public poll last election showed Senator Collins losing her re-election, and every single poll was wrong," Roderick noted. "Mainers know Susan Collins. They know her work ethic, her independence, and what her leadership on Appropriations delivers for our state."
Why 2026 Might Be Different
However, Democratic strategists counter that 2026 presents a fundamentally different environment than 2020:
Higher Unfavorability Baseline: In 2020, Collins’ favorability was roughly even in summer polls.
In 2026, her net negative approval is far more solidified. The Post-Dobbs Reality: In 2020, Roe v. Wade was still the law of the land. In 2026, voters are evaluating Collins in the aftermath of the Supreme Court's decision to overturn federal abortion protections—a decision made possible by justices she voted to confirm.
A Different Opponent Profile: Unlike Sara Gideon, who faced heavy spending attacks framing her as an out-of-state establishment politician, Troy Jackson hails from northern Maine, blunting traditional geographic attack vectors.
Act IV: The Flashpoint Issues Driving the Race
Several major policy debates are dominating the airwaves across Maine’s major media markets, shaping voter perceptions of the two candidates.
+---------------------------------------------------------------------------+
| KEY CAMPAIGN FLASHPOINTS |
+---------------------------------------------------------------------------+
| ISSUE CATEGORY | COLLINS POSITION / CAMPAIGN FOCUS |
+----------------------------------+----------------------------------------+
| Seniority & Federal Appropriations| Emphasizes chair/ranking status to |
| | secure infrastructure & defense funds. |
| Judicial Confirmations | Defends independent vetting process; |
| | recently opposed AG nominee Blanche. |
| Reproductive Rights & *Dobbs* | Maintains pro-choice stance; cites |
| | Maine's state-level abortion protections.|
+----------------------------------+----------------------------------------+
| ISSUE CATEGORY | JACKSON POSITION / CAMPAIGN FOCUS |
+----------------------------------+----------------------------------------+
| Working-Class Economics | Focuses on lowering healthcare costs, |
| | prescription drugs, and housing. |
| Judicial Accountability | Attacks Collins' 2018 vote to confirm |
| | Supreme Court Justice Brett Kavanaugh. |
| Institutional Independence | Frames Collins as a reliable vote for |
| | national Republican leadership. |
+----------------------------------+----------------------------------------+
1. The Kavanaugh Legacy and Dobbs
Perhaps no single vote in Susan Collins’ thirty-year career has generated as much enduring controversy as her October 2018 vote to confirm Supreme Court Justice Brett Kavanaugh.
At the time, Collins delivered a high-profile floor speech arguing she believed Kavanaugh viewed Roe v. Wade as "settled law" and precedent. When the High Court subsequently overturned Roe in the landmark 2022 Dobbs v. Jackson Women's Health Organization decision, reproductive rights advocates launched aggressive, multi-million dollar ad campaigns targeting the senator.
In 2026, Democratic political action committees are running ad blitzes reminding Maine voters of that vote.
2. The Battle Over Executive & Judicial Nominees
As a self-described moderate, Collins frequently faces immense pressure on judicial and cabinet nominations.
Just this month, Collins made national news by announcing her opposition to President Trump's nomination of Todd Blanche for Attorney General, citing concerns over comments regarding federal enforcement priorities.
While Collins’ campaign frames these decisions as evidence of her fiercely independent approach, critics on both sides push back:
Democrats view such votes as calculated, non-decisive shows of face-saving independence that occur primarily when a nominee already has the votes to pass.
Conservative Republicans occasionally express frustration that Collins does not vote in lockstep with the national party agenda.
3. Seniority vs. Change
Collins’ primary campaign thesis centers on her position on the Senate Appropriations Committee.
Jackson’s counter-argument focuses on economic squeeze: arguing that despite decades of Collins' presence in Washington, working-class Mainers continue to face skyrocketing housing costs, healthcare inflation, and rural hospital closures.
Act V: The "Aroostook County" Factor — A Rare Geographic Clash
In Maine politics, geography is destiny. The state is culturally and politically split into two distinct regions:
The 1st Congressional District (Southern / Coastal Maine): Heavily Democratic, wealthier, suburban, and urban (Portland, Augusta, Brunswick).
The 2nd Congressional District (Northern / Rural Maine): Culturally conservative, working-class, rural, and increasingly Republican in presidential politics (Bangor, Lewiston, Presque Isle).
MAINE'S REGIONAL POLITICAL MAP
+-------------------------------------------------------------------+
| MAINE 2ND CONGRESSIONAL DISTRICT (NORTH / RURAL) |
| - Working-class, timber, agriculture, manufacturing |
| - Home to BOTH Susan Collins (Caribou) & Troy Jackson (Allagash) |
| - Historically Collins' strong foundation |
+-------------------------------------------------------------------+
|
v
+-------------------------------------------------------------------+
| MAINE 1ST CONGRESSIONAL DISTRICT (SOUTH / SUBURBAN) |
| - Progressive, suburban, coastal, higher median income |
| - Consistently votes Democratic by double digits |
+-------------------------------------------------------------------+
Stripping the Home-Court Advantage
In past elections, Collins—who grew up in Caribou in the far northern region known simply as "The County"—enjoyed an enormous regional advantage.
Troy Jackson, however, is also a native son of Aroostook County, born and raised in Allagash.
For the first time in her five re-election campaigns, Collins is facing a general election challenger from her own home region.
Act VI: The Electoral Mechanics — Ranked-Choice Voting and the Path to 50%
Maine is one of the few states in the nation that utilizes Ranked-Choice Voting (RCV) for federal elections.
+-------------------------------------------------------------------+
| RANKED-CHOICE VOTING IN MAINE SENATE |
+-------------------------------------------------------------------+
| |
| ROUND 1: First-choice votes counted. |
| --> If a candidate achieves > 50%, they win instantly. |
| |
| ROUND 2 (If no candidate hits 50%): |
| --> Lowest-ranked candidate is eliminated. |
| --> Their voters' second-choice preferences are redistributed. |
| --> Process repeats until one candidate crosses the 50% threshold|
| |
+-------------------------------------------------------------------+
How Ranked-Choice Impacts the Strategy
Under Maine's RCV system, if no candidate reaches 50%+1 of first-preference votes on Election Night, a automatic instant-runoff count takes place.
This dynamic influences campaign behavior in two key ways:
Third-Party / Independent Candidates: Even minor third-party candidates can alter the race if their voters list Jackson or Collins as their second choice.
Preference Strategy: Neither campaign can afford to alienate voters completely. In 2018, RCV famously flipped Maine's 2nd Congressional District race to Democrat Jared Golden after second-choice preferences were tallied.
With Hart Research showing Jackson at 49% and Collins at 45%, getting across the 50% threshold without triggering a unpredictable RCV runoff is the primary goal for both campaign headquarters.
The Broader Stakes: The Senate Majority in 120th Congress
The Maine Senate race does not exist in a vacuum. It is a central battleground in the broader fight for control of the U.S. Senate.
With Republicans currently holding a narrow Senate majority, Democrats view Maine as one of their premier pick-up opportunities alongside contests in Ohio, Texas, and Florida.
+---------------------------------------------------------------------------+
| U.S. SENATE MAP CONTEXT (2026 CYCLE) |
+---------------------------------------------------------------------------+
| CURRENT SENATE BALANCE | Republicans: 53 | Democrats/Ind: 47 |
| TOTAL SEATS UP IN 2026 | 33 Regular Seats + Special Elections |
| DEFENDING SEATS | Republicans: 22 | Democrats: 13 |
| MARGIN FOR MAJORITY FLIP | Democrats need a net gain of 3-4 seats |
+---------------------------------------------------------------------------+
As hundreds of millions of dollars in advertising flow into Maine over the coming weeks, the state will serve as a national bellwether. Will voters stick with the proven seniority and moderate brand of Susan Collins, or will they opt for a structural change by sending labor-backed Troy Jackson to Washington?
Summary Checklist: Key Indicators to Watch Before Election Day
As November approaches, political analysts will be watching four critical indicators to gauge where this toss-up race is heading:
[ ] Second District Margins: Can Troy Jackson hold Collins to under a 5-point margin in rural Aroostook and Penobscot counties?
[ ] Suburban Turnout: Do suburban women in Cumberland and York counties turn out at record levels driven by reproductive rights messaging?
[ ] Debate Performances: How do the candidates perform in direct, televised statewide debates during October?
[ ] Ranked-Choice Tabulation: Do non-major candidates capture more than 3-4% of the initial vote, forcing a second-round RCV count?
