Many irregularities have not yet been fully investigated. Eleven federal senators made the following statement to US Congress:
The election of 2020, like the election of 2016, was hard fought and, in many swing states, narrowly decided. The 2020 election, however, featured unprecedented allegations of voter fraud, violations and lax enforcement of election law, and other voting irregularities.
And those allegations are not believed just by one individual candidate. Instead, they are widespread. Reuters/Ipsos polling, tragically, shows that 39% of Americans believe ‘the election was rigged.’ That belief is held by Republicans (67%), Democrats (17%), and Independents (31%).
Ideally, the courts would have heard evidence and resolved these claims of serious election fraud. Twice, the Supreme Court had the opportunity to do so; twice, the Court declined.
A fair and credible audit—conducted expeditiously and completed well before January 20—would dramatically improve Americans’ faith in our electoral process and would significantly enhance the legitimacy of whoever becomes our next President. We owe that to the People.”
— Excerpt from Joint Statement from Senators Cruz, Johnson, Lankford, Daines, Kennedy, Blackburn, Braun, Senators-Elect Lummis, Marshall, Hagerty, Tuberville, January 2, 2021, to US Congress.
Their request for an open audit was dismissed.
Could these irregularities have actually affected the election outcome?
The election was only very narrowly won in several of these states. If only two or three of the above states (totalling 36 or more electoral college votes) are found to have illegitimate results, this would call into question the legitimacy of Biden’s presidency.
As of February 2021, the district, state and supreme courts have ruled on several election fraud issues, while numerous other cases are still open. Some cases were dismissed on legal technicalities, preventing evidence from being presented and considered; but a detailed list of cases and outcomes available here show that at a national level, Trump/Republicans have so far prevailed in over 66% of cases that were decided on the merits of the evidence.
