Core Contest: Collins vs. Jackson
Incumbent Republican Senator Susan Collins, first elected in 1996, faces Democratic challenger Troy Jackson, a former Maine Senate president and fifth-generation logger. The August 6-10 poll of 1,000 registered voters shows Jackson ahead 48 % to Collins 46 %, within the poll’s ±3-point margin. The race is now viewed as a toss-up that could affect Senate control, with Democrats needing four net gains for a 51-seat majority.
Background & Context
Immigration and border security rose to second-place importance among Maine voters after the fatal July 13 shooting of Joan Sebastian Guerrero during an ICE operation in Biddeford. DHS said the officer fired because Guerrero attempted to flee; the Maine Attorney General’s Office is investigating the use of deadly force. Senator Angus King’s office clarified Guerrero was not the warrant target. The incident coincided with the withdrawal of original Democratic nominee Graham Platner amid an assault allegation, prompting Jackson’s entry.
Data & Statistics
- August 6-10 poll: Jackson 48 %, Collins 46 %; 55 % of respondents “very or extremely concerned” about Collins voting with President Trump, versus 43 % concerned about Jackson’s ties to democratic socialism.
- UNH Survey Center (July 15-20): Jackson 49 %, Collins 46 %; margin of error 2.9 pts.
- Hart Research (July 27-Aug 1): Jackson 49 %, Collins 45 %; margin of error 3.5 pts.
- Demographic strengths: Jackson leads among liberals, voters under 45, college-degree holders, and union households; Collins leads among conservatives, White evangelical Christians, voters without college degrees, and rural areas.
- Issue hierarchy: Inflation tops voter concerns; immigration/border security ranks second, followed by health care and political division.
Official Statements & Responses
Collins’ campaign defended her 2018 vote confirming Brett Kavanaugh to the Supreme Court, stating she does not regret the decision and emphasizing her support for abortion protections. The Maine Attorney General’s Office announced an investigation into the July 13 shooting, while the King office reiterated Guerrero was not the warrant target.
Criticism & Opposition
Democratic supporters argue Collins’ alignment with former President Donald Trump is a liability; a poll indicates 55 % of voters are highly concerned about this alignment. Jackson’s opponents note his past “shouting matches” with colleagues, which he has apologized for, and reference Platner’s assault allegations. Collins’ campaign counters that Jackson’s temper issues are isolated and stresses her record as a “champion for women” with a consistent pro-choice stance.
Verbatim Quotes
- “He really needs to speak to the women in Maine, and really convince them that he's going to advocate well for them,” — Stacy Leafsong

Conflicting Reports & Gaps
Poll results vary: the August 6-10 poll shows a narrow Jackson lead, while the UNH and Hart Research polls each give Jackson a two-point advantage with different margins of error. No poll provides a definitive trend on how the immigration issue will translate into votes, and granular data on independent voter behavior is limited.
What’s Next
The contest culminates on November 3, when Maine voters will decide whether Collins retains her seat or Jackson delivers a Democratic pickup. Both campaigns continue to target women, working-class voters, and independents while monitoring turnout projections and any further developments related to the July 13 ICE shooting investigation.
