The senator and twice Democratic presidential hopeful is on tour with Alexandria Ocasio-Cortez trying to build a new progressive movement. He reveals why he thinks Republicans are scared to speak up and what went wrong for Kamala Harris in 2024

‘Ithink what Trumpism is about, is an understanding that the system in America is not working for working-class people,” says Bernie Sanders, sitting in the Guardian’s offices in London. “In a phoney, hypocritical way, Trump has tapped into that. His quote-unquote ‘solutions’ will only make a bad situation worse.”

In person, Sanders’ 83 years read differently than in photograph, perhaps because of how conversational he is. His voice is magnetic – a Brooklyn accent that feels both warm and tough. “But what I have been aware of, and I’ve talked about it for years, is that in America, the very richest people are doing phenomenally well, while 60% of our people live paycheck to paycheck.”

Later, he will say the same thing to an audience in London – only with more emphasis and passion. “Sixty per cent. Six-zero. Do you know what paycheck to paycheck means?” It’s exhilarating to hear Sanders speak to a crowd: his zeal is reflected back in their faces, his moral clarity is such a relief, set against the cynicism and resignation of most of the Democratic party’s opposition to Trump and his administration. Class war is as old as time, but it’s a peculiarity of this age that you rarely hear a politician name it. “I do,” he tells me. “There is a class war going on. The people on top are waging that war.”
