Would you expand on this? By most voters do you mean registered voters? Or that Clinton didn't win a majority? From the popular vote results I've seen, Clinton won a plurality of the votes. Not that the popular vote determines the outcome of the election.
From the point of view of how electoral votes are decided (excluding faithless electors), it is determined by plurality, not majority. A state's electoral votes go to the candidate who receives the most votes (a plurality), not the one who receives more than half (a majority).
