Donald Trump stunned the political world in 2016 when he became the first person without government or military experience ever to be elected president of the United States. His four-year tenure in the White House revealed extraordinary fissures in American society but left little doubt that he is a figure unlike any other in the nation’s history.

Previous presidents aimed to unite the nation upon transitioning from campaigning to governance. However, Trump diverged, embracing political confrontation throughout his tenure. Utilising his presidential platform, he targeted various perceived adversaries, including the media, his own administration, bipartisan elected officials, and foreign leaders. His prolific use of Twitter, with over 26,000 tweets, provided unfiltered insights into his thoughts but also triggered his permanent suspension from the platform due to their contentious nature. Trump's presidency culminated in unprecedented events: he became the first president to be impeached twice, notably for inciting a Capitol insurrection, and broke tradition by skipping his successor's inauguration.

The 2020 presidential election was historic in many ways. Amid a global pandemic, with unprecedented changes in how America voted, turnout rose 7 percentage points over 2016, resulting in a total of 66% of U.S. residents casting a ballot in the 2020 election. Joe Biden defeated Donald Trump 306-232 in the Electoral College and had a 4-point margin in the popular vote. While Biden’s popular vote differential was an improvement over Hillary Clinton’s 2016 2-point advantage, it was not as resounding as congressional Democrats’ 9-point advantage over Republicans in votes cast in the 2018 elections for the U.S. House of Representatives.

President Joe Biden ushered in significant transformations in America post-Trump era. These shifts encompassed a revitalization of America's global standing, evidenced by an uptick in favorability after Biden's election. His administration prioritised diverse policy endeavours, including rejoining key international agreements like the Paris climate accord and the World Health Organization. Executive orders swiftly reversed many of Trump's policies, halting border wall construction, safeguarding DACA, combating LGBTQ workplace discrimination, and reengaging with the Paris Climate Accord.

In summary, the ongoing impact of the 2020 US presidential election encompasses political shifts influenced by the pandemic, changes in voter behaviour, potential policy alterations based on election outcomes, and historical economic trends associated with different party administrations. The 2020 US presidential elections have had far-reaching consequences across political, social, economic, and international dimensions, shaping the trajectory of the United States for years to come.
