Note: In order to avoid any misunderstandings, I am not taking a position on this for or against.
I didn’t even know this existed until a few minutes ago, but apparently there is a case on the docket of the U.S. Supreme Court, #16-907, to invalidate the results of the U.S. presidential election due to Russian hacking and calling for a re-election. My knee-jerk reaction is to say that this is a long shot, but it is intriguing.
