Maine Senate candidate Graham Platner appeared with Sen. Bernie Sanders at a “Fighting Oligarchy” rally in Portland on Monday, embracing a sharply progressive message aimed at energizing Democrats ahead of the 2026 midterms. Platner, the presumptive Democratic nominee challenging five-term Republican Sen. Susan Collins, used the stage to attack corporate power, billionaires, and what he described as a political system that rewards the wealthy while leaving ordinary Americans behind.
Speaking to a large crowd of Sanders supporters, Platner called for a “political revolution” and argued that Americans must reclaim power from corporations, rich elites, and “corrupt politicians like Susan Collins.” He framed his campaign as part of a broader populist movement, saying the current system allows politicians to become millionaires while telling voters to accept “crumbs.”
Platner also focused on economic inequality and health care, accusing insurance executives of profiting at the expense of working families. His remarks echoed Sanders’ long-running attacks on corporate influence and the concentration of wealth in the United States. The event was one stop on Sanders’ Maine tour with Platner and gubernatorial candidate Troy Jackson, designed to mobilize progressive activists and strengthen grassroots organizing.
The rally also highlighted Platner’s strong criticism of U.S. military spending and foreign policy in the Middle East. He argued that American tax dollars should be used for domestic needs such as schools and hospitals rather than for weapons used in conflicts involving Gaza and Iran. Platner said the U.S. should stop funding violence abroad and redirect resources toward problems at home.
Sanders, in turn, cast Platner as a key figure in the progressive movement and suggested that his election could help reshape national politics. He tied Platner’s campaign to his own push for a wealth tax on billionaires, saying he had introduced legislation that would impose a 5% annual tax on 938 ultra-wealthy Americans. Sanders said Platner would stand with him in fighting for that agenda.
The Vermont senator also portrayed Platner as an ally in resisting the influence of major tech billionaires such as Elon Musk and Mark Zuckerberg, warning that a small group of wealthy executives could dominate the future of artificial intelligence and robotics. Sanders said the country should not allow “a handful of billionaires” to control America’s future.
Platner’s appearance underscored how closely his campaign is aligning itself with Sanders’ democratic socialist wing of the party. The rally positioned him as a combative challenger to Collins and as part of a larger effort to turn anti-establishment energy into electoral gains. It also signaled that progressive economic populism, opposition to corporate power, and criticism of U.S. foreign policy will be central themes in Platner’s bid for the Senate seat in November.
