2020 United States presidential election

Nominations and principal candidates

The two main parties nominated experienced figures. The Republican Party re‑nominated the sitting president after he carried the field of challengers in the Republican primaries; some state Republican organizations reduced or cancelled nominating contests in support of his campaign during that stage. The Democratic contest was unusually large: dozens of candidates entered the race for the Democratic nomination, making it one of the most crowded modern primary seasons. After a lengthy selection process, former vice president Joe Biden became the party's presumptive nominee and selected Senator Kamala Harris as his running mate. Senator Bernie Sanders and other contenders had been leading figures in the primary debates and voting rounds earlier in the year.

Context and key issues

The election took place against several defining national developments. The ongoing COVID‑19 pandemic altered campaigning and voting procedures and had caused well over 200,000 deaths in the United States by the time of voting. Widespread protests and public debate followed the murder of George Floyd and prompted discussions about policing and racial justice alongside demonstrations concerning other victims and systemic issues in the Black community. The death of Supreme Court Justice Ruth Bader Ginsburg late in 2020 and the nomination that followed focused attention on the Supreme Court. Health care was a prominent campaign topic, with disputes over the future of the Affordable Care Act and proposals for its expansion or replacement.

Voting, turnout, and certification

Turnout in 2020 was among the highest in modern U.S. history. Many states expanded access to absentee and mail voting because of public health concerns, which led to a larger share of ballots cast before Election Day. Ballot counting and certification timelines differed by state; after votes were tallied, the appointed electors met on December 14 to cast their formal electoral college ballots. The process is governed by state procedures and by members of the parties in each state who certify the selection of electors. Incumbent candidates and challengers both sought to ensure that certified results reflected lawful counts rather than unfinished tallies or provisional ballots for or against incumbents.

Legal challenges and the post‑election period

In the weeks after November 3, numerous lawsuits and recount requests were filed by the Trump campaign and allied groups in multiple states. More than forty post‑election lawsuits sought to contest results, challenge procedures, or ask courts for remedies. The majority of these suits were dismissed or resolved against the challengers for lack of persuasive evidence or standing; courts issued rulings rejecting claims that would have changed outcomes in contested states during that period. Several states conducted recounts or audits that confirmed the initial counts. When Congress met to count and certify the electoral votes in early January, objections were raised by some lawmakers to results from select states, leading to extended debate before the final certification was completed.

Significance and lasting effects

The 2020 election had significant consequences for U.S. policy and politics. It underscored debates about election administration, mail voting, and the role of courts in resolving disputes. Voters’ responses to public health management, economic conditions, racial justice protests, and judicial appointments shaped both the campaigns and the policy priorities of the incoming administration. The election also stimulated renewed attention to the mechanisms of the Electoral College and to how states certify and protect voting processes.
