The world has just witnessed a historic turn. Donald Trump’s election as America’s 47th president was not a fluke: his victory was decisive. By securing more than 70m votes, he has won the popular vote for the first time in three attempts. The Republican Party now runs the Senate and is likely, within days, to secure control of the House. Add that the Supreme Court will be firmly entrenched with MAGA values for a generation. All this constitutes a stunning comeback and provides a powerful mandate for Mr Trump; in our cover leader we call him the most consequential American president since Franklin D. Roosevelt.

Our weekly edition considers what a second Trump presidency means. If Mr Trump has wrecked the old order, what will take its place? Will the return of Trumponomics spark a global trade war? How will Mr Trump handle the conflicts in Ukraine and the Middle East? His sweeping victory could set the tone for fellow nationalist populists such as Marine Le Pen, who hopes to secure France’s presidency in 2027. Mr Trump was too easily dismissed as an aberration in his first term. Not now. He has defined a new political era, for America and the world.

Subscribers can now sign up to participate in our live digital event on Friday November 8th, where our editors will discuss the election’s aftermath and what comes next. I also recommend the US in brief, our daily newsletter devoted to the most important matters in American politics.

Wherever you live, Mr Trump’s presidency will affect you. Over the next four years, we will report on and analyse the effects of the second Trump presidency on policy, business, economics and more—in America and around the world.
