Wendy, respectfully, your own comment says that "she lost by so few votes that anything could have tipped the scales the other way" so how can that sync with "the mistakes she made were probably not enough to cost her the win"?
I mean, sure, I think any presidential candidate who loses a tight race is going to feel bitter about aspects of it, especially if one feels the other side used below-the-belt methods, but I'm also a person who played competitive sports and when our team lost a close game, our coaches always taught us NOT to focus on calls that didn't go our way from the umpires, but rather to look at the mistakes we made and to learn and GROW from them so we can become better.
