Susan Collins faces political survival test as Maine Senate race tightens ahead of midterms
By Sadaf Sundas Riaz — SCN NEWS
WINDHAM — Republican Senator Susan Collins is fighting one of the most difficult re-election campaigns of her three-decade congressional career as Maine voters weigh her reputation for political independence against growing dissatisfaction with President Donald Trump's economic policies, in a closely contested race that could help determine control of the United States Senate.
Collins, who first entered the Senate in 1997, is the only incumbent Republican seeking re-election in a state that voted against Trump in the 2024 presidential election. Her Democratic challenger, former Maine Senate President Troy Jackson, has turned the contest into a referendum on the consequences of Republican policies, arguing that Collins has failed to use her influence in Washington to prevent economic hardship. Recent opinion polls show the candidates running close together, leaving the outcome uncertain with one week remaining before the November 3 midterm elections.
The contest has become particularly significant because Republicans hold a 53–47 majority in the Senate, including the two independents who caucus with Democrats. Democrats need a net gain of four seats to secure control of the chamber, making Maine one of their most important opportunities to defeat a Republican incumbent. The result could influence the balance of power in Washington during the remaining two years of Trump's presidential term, including congressional oversight, federal spending decisions and the confirmation of senior administration officials.
Collins has survived previous Democratic challenges by presenting herself as a moderate Republican willing to break with her party on selected issues. That political identity has helped her win repeated elections in a state that has generally supported Democratic presidential candidates. However, the increasingly polarised national political environment has narrowed the group of independent and crossover voters who previously helped sustain her electoral coalition.
Her campaign has focused heavily on the benefits Maine has received from her seniority and her position on the powerful Senate Appropriations Committee. Collins says she has secured nearly $1.5 billion in congressionally directed spending since 2021, supporting projects ranging from wastewater treatment infrastructure and harbour improvements to emergency medical facilities. She argues that her experience and relationships in Washington provide practical advantages for a relatively small state competing for federal resources.
Recent campaign appearances have taken Collins to infrastructure and public-service projects across Maine, including a wastewater treatment facility in North Windham, a dock in Bucksport and an emergency centre in Farmington. Those visits have allowed her to connect federal spending decisions with services used by local communities while presenting her record as evidence that she can obtain resources regardless of which political party controls the White House.
Jackson has challenged that argument, saying the benefits Collins claims to have secured cannot compensate for the broader economic consequences of policies pursued by Trump and congressional Republicans. A former logger from the northern Maine community of Allagash, Jackson has emphasised his working-class background while campaigning for expanded healthcare access and higher taxes on wealthy Americans. He argues that the central question is not whether Collins can negotiate exceptions to federal policies, but whether those policies should have been adopted in the first place.
The dispute has become especially visible over Trump's trade measures against Canada, which have affected businesses in a state with substantial economic connections to its northern neighbour. Maine's agricultural producers, construction companies and manufacturers depend on cross-border trade, making tariffs and restrictions on imported materials a prominent issue. Collins has pointed to exemptions secured for road salt, cement and equipment used by blueberry, potato and apple growers as examples of her ability to protect local economic interests.
Jackson argues that such exemptions provide only limited relief from policies that have already increased costs and created uncertainty for businesses. He has criticised congressional Republicans for allowing the administration broad discretion over tariffs, saying lawmakers should exercise greater authority over trade decisions affecting their constituents. The disagreement reflects a wider debate over whether an experienced senator's ability to obtain targeted concessions outweighs the consequences of policies supported by the senator's party.
Energy prices have added another source of pressure. Home-heating oil is particularly important in Maine, where approximately half of households rely on it for heating, leaving residents exposed to fluctuations in global petroleum markets. Prices have increased by more than 70% over the past year amid disruption linked to the war with Iran, according to Reuters reporting, intensifying concerns about household expenses as colder weather approaches.
Collins has highlighted her role in securing the release of federal home-heating oil reserves as an attempt to reduce the financial burden on residents. Jackson has responded by linking the increase in energy costs to the administration's foreign policy, arguing that emergency measures cannot fully offset the effects of the conflict. The issue has brought international developments into a Senate campaign otherwise dominated by local economic concerns and the candidates' records in public office.
Healthcare has become another major dividing line. Collins points to a $50 billion federal fund intended to support rural hospitals facing financial pressure following healthcare spending reductions included in the 2025 tax and spending legislation. She presents the programme as evidence of her ability to negotiate protections for vulnerable communities, particularly in a state where rural residents often face long journeys to reach medical facilities.
Jackson and other Democrats argue that the fund does not resolve the underlying consequences of the spending reductions. They maintain that rural hospitals and patients would be better served by avoiding the cuts rather than creating separate programmes to offset their impact. The debate has become a test of competing approaches to federal spending, with Collins defending targeted intervention and Jackson calling for broader changes to healthcare financing.
The election has also been shaped by disagreements over immigration enforcement and public safety. Collins has highlighted funding for body-worn cameras and de-escalation training for federal immigration officers following the January deaths of two U.S. citizens in Minnesota. Jackson has questioned whether those measures are sufficient, pointing to the subsequent killing of a Maine resident by an immigration officer in July as evidence that additional accountability is needed.
The Democratic campaign experienced significant disruption earlier in the year when Graham Platner, an oyster farmer and Marine veteran, withdrew after facing a rape accusation that he denied. Jackson subsequently emerged as the party's replacement candidate, forcing Democrats to reorganise their campaign during the summer. Despite the late change, the party has consolidated around Jackson, and the race has remained highly competitive.
The campaign has attracted extraordinary financial attention from political parties and outside organisations. Advertising analysis firm AdImpact estimates that spending connected to the contest will reach approximately $199 million, an amount equivalent to roughly $170 for every adult resident of Maine. Television viewers have encountered repeated advertisements from both sides, reflecting the importance national political organisations attach to the result.
The spending has been concentrated on a relatively small number of voters who remain open to changing their preferences. Campaign workers in Windham, a suburb of Portland, report that many residents have already decided which candidate they support. The community is politically significant because Collins carried it by a substantial margin in 2020 even as its voters supported Democrat Joe Biden for president.
That history illustrates the challenge facing both campaigns. Collins must retain enough voters willing to distinguish her individual record from the national Republican Party, while Jackson must persuade some previous Collins supporters that the senator's independence no longer provides sufficient protection against policies they oppose. Recent interviews conducted by Reuters indicate that some residents who previously backed Collins are now supporting Jackson because of their dissatisfaction with the Republican Party under Trump.
Collins has also sought to reinforce her moderate image by campaigning alongside former Senator Joe Manchin, who left the Democratic Party in 2024 and became an independent. Their joint appearances have emphasised bipartisan cooperation and the importance of relationships across party lines. Jackson, meanwhile, has received support from prominent progressive Democrats, highlighting the different political coalitions each candidate is attempting to assemble.
The competing campaigns have raised questions about the future of moderate Republicans in states increasingly divided along national party lines. Collins has maintained an electoral position that has become unusual in contemporary American politics, repeatedly winning support from voters who favour Democrats in presidential elections. Whether that distinction remains persuasive is now central to her effort to secure a sixth Senate term.
The race also demonstrates how national economic and foreign policy decisions can reshape local elections. Trump's tariffs, the conflict with Iran, federal healthcare spending and immigration enforcement have all become subjects of debate in Maine, even as Collins and Jackson emphasise their personal records and competing approaches to representing the state.
With the election scheduled for November 3, neither candidate has established a decisive advantage. The outcome will depend in part on whether Maine voters place greater weight on Collins' seniority and record of obtaining federal resources or on Jackson's criticism of the administration's policies and their effects on households and businesses.
For the Republican Party, Collins' survival would preserve a Senate seat in a state that has increasingly favoured Democrats in national elections. For Democrats, defeating her would represent an important step towards challenging Republican control of the chamber. The closely contested race leaves both possibilities open as Maine approaches election day.
