Yes.
The act of 50 Secretary’s of State allowing him on the ballot, the Electorial Collegiate casting their votes for him and the certification of the election of by Congress and the subsequent oath of office given by the CJ-SCOTUS and the aside fact that the Clinton’s didn’t use any information contrary in their campaign and that he won both popular and collegiate vote — means that I can with a degree of certainty say yes.
