Just calling them “mistakes” is being overly kind IMO.

"Just calling them mistakes is being overly kind . . . "

That was my initial reaction, but she begins the article by pointing out how the media accuses Trump of "lies" when they are merely opinions, failed aspirations, exaggerations, honest mistakes, or even the opinions of reporters. So she doesn't want to fall into the same trap, and is not making the value judgment that these were "lies," but simply that they were wrong.
