What does it matter? People voted, the vote was counted, the man isn't President.What is it you think didn't work exactly? What about the election process is inherently broken that states now need to, I think legally questionably, usurp voters.
Now if States want to take him to task for pressuring to 'find the missing' or 'discrepant votes' and there is a legal issue with it then that's what due process clause is supposed to jump start.
