Taylor Swift’s Instagram endorsement, the latest in a series of American celebrities to declare their support for Kamala Harris in the 2024 presidential race, has marked the beginning of the final phase of the U.S. electoral campaign. Across the Atlantic, the European Union is closely watching the competition between Harris and Donald Trump, fully aware of the global repercussions. Harris, with her progressive vision, embodies the hope for an America ready to strengthen transatlantic ties and promote cooperation on crucial issues like climate change and global security. On the other hand, Donald Trump, with his incendiary rhetoric and isolationism, sends shivers down the spines of European leaders, who fear a return to the tensions and disengagement that characterized his first term. A potential Trump victory could push the United States on a collision course with Europe, endangering the stability of transatlantic relations. The contest between Harris and Trump is much more than a simple American election: it is a battle for the future of global relations, with Europe rooting for an America that does not isolate itself but continues to build bridges.
