I hate to kill people’s buzz but U.S. vs. Throckmorton had nothing to do with elections.

-SB
"3. The cases where such relief has been granted are those in which, by fraud or deception practiced on the unsuccessful party, he has been prevented from exhibiting fully his case, by reason of which there has never been a real contest before the court of the subject matter of the suit."
"4. The circuit court of the United States has now no original jurisdiction to reform surveys made by the land department of confirmed Mexican grants in California."
In other words, there is precedent that fraud vitigates, which means it makes void (like a void check) or annuls. In other words. The election would be null and void because of the extent of fraud. And there's only 2 ways to fix that. 1. Revote the whole thing, or 2. go to the House (based on State Legislators NOT current makeup proportions) and the Senate would pick the VP. Which is one reasons why they want the Senate. Can you imagine President Trump with VP Kamala Harris? It is theoretically possible I believe. Such a rare situation though.
