Donald Trump has spat out so many insults and broken so many taboos that it’s hard for any single remark to linger long in the memory. Nevertheless one line from his 2016 election campaign has endured, partly because it was a jaw-dropper and partly because it offered an early glimpse of what would later be revealed as a deep truth about both his candidacy and his presidency – and even our current world.

Donald Trump has spat out so many insults and broken so many taboos that it’s hard for any single remark to linger long in the memory. Nevertheless one line from his 2016 election campaign has endured, partly because it was a jaw-dropper and partly because it offered an early glimpse of what would later be revealed as a deep truth about both his candidacy and his presidency – and even our current world.

For most progressive-minded, remain-leaning folk, is it even a dilemma? I’m not sure. To them the logic must seem simple and straightforward: they want to eject a cruel and useless government and stop Brexit, and that means denying Boris Johnson a majority and replacing him with Jeremy Corbyn, who will end austerity and hold a second referendum. Job done.

Say it like a catechism, every morning, every evening and twice before meals: no one knows what will happen, no one knows what will happen, no one knows what will happen. This is as unpredictable an election as there’s ever been, with voter volatility at record highs and party allegiance at record lows. No one knows how the divisions within the competing tribes of leave and remain will play out: will Nigel Farage hive off pro-Brexit voters from the Tories and so boost Labour, or could it be the other way around? As the late screenwriter William Goldman so famously said of Hollywood: “Nobody knows anything.”
