Answer: LACK OF EVIDENCE
Explanation: The 2020 Presidential election was one of the most closely watched and controversial elections in recent history. After the election, many claims of voter fraud were made by supporters of former President Donald Trump and other individuals, but these claims were thoroughly investigated by election officials, and in many cases, by courts.
The vast majority of these claims were found to be baseless and lacked evidence to support them. Courts, including the Supreme Court of the United States, reviewed multiple lawsuits alleging voter fraud and found that there was no evidence of widespread fraud that would have impacted the outcome of the election.
In several instances, individuals who made false claims of voter fraud were even charged with crimes such as perjury, obstruction of justice, and making false statements to federal agents.
The results of the 2020 election were certified by Congress on January 6, 2021, and Joe Biden was inaugurated as the 46th President of the United States on January 20, 2021.
It is important to note that allegations of voter fraud should always be taken seriously and thoroughly investigated. However, in the case of the 2020 presidential election, the vast majority of claims were found to be baseless, and the election results were upheld.
