Nothing has absorbed Maine politics like the candidacy of Graham Platner. Almost from the moment he announced his run for the U.S. Senate in mid-August 2025, he drew big crowds and lots of attention. His strongest backers stuck with him through controversy after controversy until Jenny Racicot publicly accused him of sexual assault. Platner denied the allegation, but his support collapsed.

Yet even after Platner officially withdrew as the nominee on July 10 and the Maine Democratic Party began the process of replacing him, it seemed like Mainers were going to keep talking about him for a while. Many of his committed voters were deeply disappointed about what they learned; others were very angry that the news had been revealed. Some suggested they might write in Platner’s name or not vote at all in the fall. 

Then came an awful event that starkly shifted Mainers’ attention, and moved the focus of the Maine Senate race from Platner to Sen. Susan Collins.

The killing of 26-year-old Johan Sebastián Durán Guerrero in Biddeford, Maine, on Monday was a real shock in the state. Maine often has the lowest rate of violent crime nationally and homicides are rare, with only 21 in 2025.

Maine, like Minnesota, is a highly participatory state, and both places responded similarly to ICE incursions this past winter. 

Of course, it wasn’t just Guerrero’s death that was the story, but also who shot him — an Immigration and Customs Enforcement officer — and the circumstances of his killing. For one, unlike other shootings by ICE officers, the Department of Homeland Security did not even claim that Guerrero posed any sort of imminent threat or that the shooter feared for their life. Rather, DHS said that Guerrero’s “vehicle attempted to flee the scene and, fearing for public safety, an officer discharged his weapon.”

Moreover, Guerrero was legally in the country, according to local immigrant rights groups. And Sen. Angus King, I-Maine, said Guerrero wasn’t even the person ICE was seeking.

Witnesses were shaken by what they saw. One bystander, Daniel Boucher, “choked up” recounting his experience, reported The Associated Press. “His face was bloody. His head was bloody,” Boucher said of the victim. “I clearly heard the victim say, ‘I tried to stop.’” Em Akerley, another neighbor who heard the shots and looked out the window to see some of what happened, told a local news station, “You know, it shatters the illusion that Maine is safe … I don’t know what he did, but he didn’t deserve to be executed in the street.”

Mainers quickly mobilized, with demonstrations in Biddeford, Portland, Bangor and Scarborough. “This is a land for people who want to be here,” said one rallygoer. “It doesn’t matter who you are, where you came from, what color your skin is. That’s what America is about.”

Both Senate candidates and members of the public criticized Collins. Protesters in Biddeford crowded the doorway at the senator’s local office, shouting, “Vote her out!” Senate candidate Shenna Bellows argued that she had already acted when, as secretary of state, she blocked ICE from getting undercover license plates and proclaimed, “There should be no secret police in our state.” Another contender, Troy Jackson, referred to “ICE’s rogue actions” and blasted Collins for voting “to send $70 billion dollars to ICE with no reforms.” A third potential Democratic nominee, Nirav Shah, contended, “There is a straight line from Sen. Collins to the lawlessness we saw yesterday.” 

While, as I’ve noted, some Platner supporters were deeply unhappy that he wasn’t going to be the Democratic nominee, his absence in the aftermath of the shooting didn’t seem to matter in the least.

And why should it have? Maine, like Minnesota, is a highly participatory state, and both places responded similarly to ICE incursions this past winter. 

Collins tried to claim credit for ending the winter surge. But Democrats and immigrant rights leaders were skeptical and pointed to her support for increased ICE funding without any reforms. 

In both places, ICE showed up with face masks and randomly detained people, including those in the country legally. Agents smashed in the car windows of a University of Maine-trained civil engineer, Juan Sebastián Carvajal-Muñoz, and took him away with the car still running. He had a valid permit to work, an engineering job and no criminal record. A man training to be a corrections officer in southern Maine suffered the same fate, and as did others, including asylum seekers.

Then, as now, Mainers came together, sometimes via social media and sometimes through various groups, to try to counteract ICE.

As in Minnesota, ICE was heavy-handed and showed disrespect for civil rights. Two Maine women observing ICE were told they would be put on a domestic terrorist watch list and sued. “Only 11 of the nearly 200 people detained in Maine during a massive January immigration enforcement surge were recorded as having a criminal record,” the Bangor Daily News reported, making ICE look even more abusive.

At the time, Collins tried to claim credit for ending the winter surge. But Democrats and immigrant rights leaders were skeptical and pointed to her support for increased ICE funding without any reforms. 

Now, Collins is again responding in her classic both-sides way. On the one hand, the incumbent urged DHS Secretary Markwayne Mullin “to cease all non-urgent vehicle stops” and tepidly acknowledged that the lack of a recording device on the shooter was “extremely unfortunate.” On the other hand, Collins blamed Democrats for a delay in body cameras and contended that eliminating ICE “would make our country less safe.”

Platner’s fall upended the state’s biggest race for a time. But there are plenty of ICE critics, both political leaders and not, who are taking charge of the response to Collins and the agency.

And, though the Democratic Senate nominee is unknown again, Mainers are rising up, speaking out and moving on.
