In a highly competitive Senate race in Maine, Republican Senator Susan Collins and her Democratic challenger, Troy Jackson, are employing starkly different strategies as Election Day approaches. Their campaigns have attracted prominent political figures who represent divergent wings of the Democratic Party, underscoring broader national tensions within the party.

On Wednesday, Collins was joined by former Senator Joe Manchin III of West Virginia, a centrist Democrat turned independent who endorsed her campaign. Together, they visited locations in politically mixed areas such as a New Balance factory in Norway, Maine, aiming to appeal to moderate and independent voters. Manchin, who left the Democratic Party in 2025 citing its shift to the left, praised Collins as “the best senator in America” and emphasized bipartisan cooperation. Collins, 73, has maintained a reputation as a pragmatic Republican capable of working across the aisle, a key factor in her enduring popularity in this traditionally Democratic-leaning state. She has sought to portray Jackson as too far left for Maine, especially noting the state’s older demographic. Collins has faced criticism from Democrats over her vote to confirm Supreme Court Justice Brett M. Kavanaugh, a decision that has been heavily scrutinized amidst ongoing debates about abortion rights.

Jackson, 58, who secured the Democratic nomination after the withdrawal of another progressive candidate amid controversy, has been energizing more progressive and younger voters. His campaign has been bolstered by visits from prominent left-leaning Democrats, including Representatives Alexandria Ocasio-Cortez, Bernie Sanders, and Elizabeth Warren. Ocasio-Cortez, speaking at a theater in Portland, Maine’s largest city, encouraged voters to turn out and bring friends to support Jackson, praising his willingness to campaign “his way” alongside her despite potential political risks. Jackson emphasized the importance of having outspoken progressive voices in government and highlighted his appeal to voters seeking change after years of Republican influence at the federal level.

The contrasting endorsements from Ocasio-Cortez and Manchin reflect the broader ideological divide within the Democratic Party. Ocasio-Cortez, a rising figure considered a potential 2028 presidential contender, has criticized the party’s centrists for an affinity for corporate interests and lack of progressive ambition. Meanwhile, Manchin represents a more moderate, pragmatic faction that resonates with independents and conservative Democrats. Some analysts suggest that Ocasio-Cortez’s involvement could mobilize the Democratic base but might risk alienating moderate voters, whereas Manchin’s presence with Collins aims to reinforce her bipartisan appeal.

Local voters express mixed views on the campaign. Some view Collins as a reliable moderate willing to work across party lines, while others see her as aligned too closely with Trump-era policies. Meanwhile, Jackson’s progressive message, amplified by Ocasio-Cortez, appeals to voters desiring more assertive change, particularly among younger demographics. The race remains closely watched as a potential bellwether for Senate control, with less than two weeks until voters decide whether to continue with Collins or opt for Jackson’s progressive agenda.
