Why did Doge, the bureaucracy-slashing project of Donald Trump’s administration, fizzle after 130 chaotic days? The volatility of Elon Musk, its architect and enforcer, was a big factor. Zia Yusuf has another theory, which carries weight because of who he is: Nigel Farage’s right-hand man heads “Reform UK DOGE”, as Britain’s hard-right party terms its own cost-cutting unit. Mr Musk’s main obstacle, he says, was the insistence of America’s Founding Fathers that Congress controls the federal budget to which Mr Musk sought to take a chainsaw.
