Final answer:
The 2020 United States Presidential Election was declared as the safest and most closely supervised in American history due to enhanced security measures, high voter turnout facilitated by provisions arranged due to the COVID-19 pandemic, and close observance by independent international and domestic observers.
Step-by-step explanation:
The election being referred to in the question is the 2020 United States Presidential Election where Joe Biden and Kamala Harris ran against the incumbent President Donald Trump and Vice President Mike Pence. Despite occurring during the unprecedented circumstances of the COVID-19 pandemic, this election was pronounced as the safest and most closely supervised in American history.
Safety was ensured through enhanced security measures to limit election fraud or interference. This includes steps such as comprehensive fact-checking, monitoring of election hardware and software, additional supervision on tallying procedures, and usage of paper records of each vote to ensure the accuracy and legitimacy of votes. High voter turnout was recorded, in part due to measures put in place to facilitate voting during the pandemic, such as expanded early voting and absentee, vote-by-mail options.
In addition, the 2020 election was closely observed by independent domestic and international observers to affirm that it adhered to international standards of a free and fair election. The high level of scrutiny provided additional credibility to the election proceedings and results. Thus, election experts have crowned it as the safest and most carefully monitored election in American history.
