2020 Presidential Election

Trump secured the Republican nomination without serious opposition, while Biden secured the Democratic nomination over his closest rival, Senator Bernie Sanders, in a competitive primary that featured the largest field of candidates for any political party in the modern era of American politics. Biden's running mate, Senator Harris from California, was the first African-American, first Asian-American, and third female vice presidential nominee on a major party ticket.

Central issues of the election included the public health and economic impacts of the ongoing COVID-19 pandemic; civil unrest in reaction to the killing of George Floyd and others; the U.S. Supreme Court following the death of Ruth Bader Ginsburg and confirmation of Amy Coney Barrett; and the future of the Affordable Care Act.

The election saw a record number of ballots cast early and by mail due to the ongoing pandemic. As a result of the large number of mail-in ballots, some swing states saw delays in vote counting and reporting; this led to major news outlets delaying their projection of Biden and Harris as the winners until the morning of November 7. Before, during, and after Election Day, Trump and numerous Republicans attempted to subvert the election and overturn the results, falsely alleging widespread voter fraud and trying to influence the vote counting process in swing states. Attorney General William Barr and officials in each of the 50 states found no evidence of widespread fraud or irregularities in the election. Federal agencies overseeing election security said it was the most secure in American history.
