Welcome to Trump’s America, The i Paper’s World Insight series presenting the sharpest, deepest thinking on an era-defining shift in history and politics, investigating how Donald Trump and his administration have changed the US and the world – and where we go from here.

• America can’t afford to retire• The US is becoming impossible to live in• The White House I worked for would have condemned this image. Trump refuses• Maga leaders want ‘traditional American families’ – but can’t stop having affairs• Sin City has lost its shine. It shows how far America has fallen• The Florida street that exposes America’s growing homophobia• Inside America’s most loyal Trump town – where people still think he’s ‘a good man’

Donald Trump is governing like a president drunk on power. The shift is unmistakeable. He no longer faces the constraints that once shaped his behaviour. He does not have to run for re-election. He is surrounded by loyalists who reinforce his worst impulses. The Supreme Court has granted him sweeping immunity. The guardrails that once restrained him have fallen away, leaving a president operating with a sense of freedom that has pushed him further from the responsibilities of the office and deeper into his own preoccupations.
