Clinton didn't create the term fake news. The article you link to mentions her having used the term in a speech, but that doesn't mean she created it, nor, as I assume we're meant to infer, that she or the Democratic Party fabricated the phenomenon referred to as a post-hoc rationalization for having lost the election.

In fact, if you read the Wikipedia article on fake news[0], you'll note the term as well as the phenomenon predate Clinton's campaign and loss, even within that campaign cycle. People were talking about it well before that point.
