There is no shortage of 2020 Election Fraud conspiracy theories in the United States, and there was no shortage of attempts to overturn the final result of the Presidential Election. None of the processes that the United States uses to adjudicate matters like these led to any substantial changes (if any) of the final results.
One premise that came to mind may have acted as a double-edged sword had any of the lawsuits been successful. This premise is the reality that several elections for office are held on the same ballot card. Because multiple elections are held on one ballot, I would assume that if it was discovered that one election was fraudulent, then all elections on that ballot would be contaminated as well. However, this mechanical reality of voting never seemed to be addressed in the many allegations of fraud that were made...which would seem to be a vital premise to at least address, lest other elections be held under scrutiny that the accuser did not intend to hold under scrutiny.
However, because it was not explicitly addressed, it seems that the situation described in the second paragraph wasn't the case. It is this crucial scenario, and the lack of addressing it that led me to ask the following question:
If multiple elections are held on the same ballot, how could alleged voter fraud in one of the offices not lead to consequences for the other offices on the ballot?
