Donald Trump, the 45th president of the United States (2017–2021) ran a successful campaign for the 2024 U.S. presidential election. He formally announced his campaign on November 15, 2022, initially battling for the Republican Party's nomination. While many candidates challenged the former president for the nomination, they did not manage to amass enough support, leading Trump to a landslide victory in the 2024 Iowa caucuses. On March 12, 2024, he became the Republican Party's presumptive nominee. Trump was officially nominated on July 15 at the Republican National Convention, where he chose JD Vance, the junior U.S. senator from Ohio, as his vice presidential running mate. On November 5, Trump and Vance were elected president and vice president of the United States, winning all seven swing states as well as the popular vote with a plurality.
