There were plenty of dubious factors that could have tipped the scales for a Biden victory, including machinations by the Federal Bureau of Investigation.

The Long History of FBI Abuse
Though the media usually portray the FBI as the ultimate good guys, the bureau has long history of intervening in presidential elections. Shortly after taking office after Franklin Roosevelt's death, President Harry Truman commented in his diary: "We want no Gestapo or Secret Police. FBI is tending in that direction. They are dabbling in sex-life scandals and plain blackmail…This must stop." But FBI Director J. Edgar Hoover outfoxed Truman and every subsequent president.

In the 1948 presidential campaign, Hoover brazenly championed Republican candidate Thomas Dewey, leaking allegations that Truman was part of a corrupt Kansas City political machine. In 1952, Hoover sought to undermine Democratic presidential candidate Adlai Stevenson by spreading rumors that he was a closet homosexual.

In 1964, the FBI illegally wiretapped Republican presidential candidate Barry Goldwater's presidential headquarters and plane and conducted background checks on his campaign staff for evidence of homosexual activity. The FBI also conducted an extensive surveillance operation at the 1964 Democratic National Convention to prevent embarrassing challenges to President Lyndon Johnson.
