Was it sexism or clintonism?

In reading today's New York Times Article, "Critics and News Executives Split Over Sexism in Clinton Coverage", I asked myself, was the medias bias against Hillary mostly sexism or clintonism? My initial conclusion, although after just a brief amount of thought, is that it was about 80% clintonism. The worst biases, though, were the bias against substance and towards the superficial, and the bias against reporting important truths in a non-misleading way and towards being "even -handed", i.e. We'll report the Republicans say, "The Earth is flat". The Democrats say, "The Earth is round", and we'll never tell you that scientists have conclusively proven it's round.
