It's not just who wins but why he or she won, and in Hillary's case, it was her poor judgement that cost her the election. Days before the election was over, the polls showed the race tightening, and Trump campaigned hard in swing states that held critical electoral vote, but Hillary spent her time in California, a state she had already won by a large margin. That was just poor judgement and that poor judgement cost her the election. Had she spent the last few days stomping hard in those close mid western states instead of in California, she might have become president.
