Maine Democrats Debate as ICE Shooting Fuels Senate Race

Protests erupted across Maine following the fatal shooting of a 26-year-old Colombian immigrant by an ICE agent in Biddeford. Community organizers and Democratic candidates quickly assembled rallies near the site of the shooting, drawing scores of protesters who marched from City Hall to Republican Senator Susan Collins' office.

Zach Heiden, chief counsel at ACLU Maine, told rallygoers that their small town had joined other communities where encounters with federal immigration agents have been fatal. Investigations into the shooting are ongoing as Democrats grapple with selecting a new candidate to run for the Senate in November's midterm elections.

Four top candidates vying to replace Graham Platner as the Democratic U.S. Senate nominee in Maine took to the debate stage on Thursday. Secretary of State Shenna Bellows, former Maine Senate President Troy Jackson, former Maine Center for Disease Control and Prevention Director Nirav Shah, and ex-congressional aide Jordan Wood made their case for why they should face Republican Senator Susan Collins in November.

The Democratic candidates repeatedly attacked Collins and President Donald Trump rather than tearing one another down on stage. They criticized Collins' support for immigration enforcement funding without guardrails and her vote to advance the One Big Beautiful Bill's nearly $1 trillion in Medicaid cuts despite voting against its final passage. Shah stood out as the most skilled debater, invoking what he called the infuriating 'murder' of Joan Sebastian Guerrero by an ICE agent in his opening statement.

Senator Susan Collins faced criticism over her role in funding ICE with $70 billion without accountability measures. In a statement earlier on Tuesday, she said the shooting 'raises sufficient critical questions' and that she urged Homeland Security Secretary Markwayne Mullin to cease all non-urgent vehicle stops.

The killing has thrust immigration enforcement into sharper focus in Maine as Democrats grapple with selecting a new candidate to run for the Senate in November's midterm elections. The Maine Democratic Party has until July 27 to select a new nominee, with the nominating convention scheduled for July 25 in Bangor.

On a sunny Sunday, Senate hopeful David Costello worked the sidewalk in downtown Brunswick asking for signatures. 'Would you happen to be a registered Democrat?' he asked one woman before engaging in a back and forth conversation. She asks if he's progressive. 'Very progressive,' Costello said. Costello is one of several Maine Democrats who see the fall of Graham Platner's senate campaign as an opportunity to represent Maine in Washington.

Platner won June's Democratic primary election handily. But allegations of rape by a former romantic partner last week forced him to drop out of the race. It leaves Maine Democrats scrambling to find a new nominee before the July 27 deadline to put a name on the ballot. Platner denies the allegations.

The Maine Democratic Party will hold a convention on July 25 where 601 delegates will choose that nominee. That candidate will need to capitalize on the enthusiasm Platner generated to defeat Republican Sen. Susan Collins. Democrats see Maine as pivotal to their chances to retake the Senate.

President Donald Trump posted on Truth Social calling for ICE not to give up traffic stops, one of its 'most important and effective Crime Fighting tools.' This post complicated Senator Susan Collins' political position as she had urged Homeland Security Secretary Markwayne Mullin to cease all non-urgent vehicle stops. Despite this, Collins reiterated her position on Wednesday, telling reporters that stops should be halted until an investigation is complete.

Political experts across Maine said the president's post was unhelpful to Collins, who is vulnerable as the only Republican senator up for reelection this year in a state that Democrat Kamala Harris won in 2024. Republicans hold a 53-47 majority in the chamber, and flipping Maine is critical to Democrats' path to winning control of the Senate in the midterm elections.

Many declared candidates ran for governor or the U.S. House of Representatives in the June 9 primary, including Secretary of State Shenna Bellows, former Maine Senate President Troy Jackson, former Maine Center for Disease Control and Prevention Director Nirav Shah, ex-congressional aide Jordan Wood and social worker Paige Loud.

Mark Brewer, a political science professor at the University of Maine, said immigration has undoubtedly shifted the focus in Maine's Senate race. 'It was all Platner and Platner fallout. None of that was good for the Democrats,' Brewer said. 'Collins, I think, was probably smartly just kind of being quiet, keeping her head down and letting that be the story, and then all of a sudden ICE becomes the story.'

Experts said Democrats could still unseat Collins, who has proven adept at winning reelection and will have a massive financial advantage over the new Democratic nominee. Her campaign raised more than $4 million between April and June, according to a filing on Wednesday, entering July with an $11 million war chest.

Collins has held her seat since 1997, winning reelection in 2020 by nearly nine percentage points as Democrat Joe Biden carried the state by almost the same margin. 'There's very little question in my mind that it is' still a competitive race, said Jim Melcher, a political science professor at the University of Maine at Farmington.
