The 2024 presidential election, pitting Joe Biden against Donald Trump, may feel like a tiresome rematch of should-be retirees facing off once again with the future of the free world at stake. But something feels different and hard to explain this time. Trump’s most visible supporters are no longer angry blue-collar workers from red states wearing MAGA hats and waving “drain the swamp” signs at rallies. They’re some of the most successful businessmen in the country, expressing their grievances online, fretting about immigration and the war in Ukraine and slinging around doubts about Biden’s performance and age.
