Absolutely not. The process for electing the President of the United States is laid out clearly in the U.S. Constitution. Any court that ordered a "new election" would be operating completely outside the bounds of any constitutional authority.

The issue is absolutely not clear cut, although, as I stated, the present Supreme Court doesn't have the courage do order one:

No state or county has ever held a presidential redo election. Whether they can is an open question. On July 6, 2017, FiveThirtyEight's Julia Azari wrote, "[W]hether this kind of re-do is allowed for presidential elections is a more complicated matter. Some legal scholars maintain that the language in Article II of the Constitution prevents holding a presidential election again ... Others suggest that there is legal precedent for a presidential re-vote if there were flaws in the process

1. What would be the legal authority any Federal court would have in ordering a “re-do” of a presidential election?

2. Who would have the authority to define what exactly constitutes “flaws in the process?”

Letting courts into this process would be a nightmare. I’m really surprised anyone on this site wouldn’t recognize that.
