Total nonsense, Hillary Clinton ran for President of the United States, she is a Democratic icon and leader.
Excusing her behavior is pathetic.
Using words like nonsense and pathetic distracts from the logic of the underlying argument, unless that is what you're going for. So does trying to argue that someone else did the same thing, and trying to shift the argument to saying that someone else was in the same position as the president.
I'm not trying to justify what Hillary Clinton said. I agree with you that saying such words undermines our democracy and the legitimacy of our elections.
When someone who is not just running for President, but is a President, says stronger words that they are a bad loser and that they don't know if they will accept the results of the election, it undermines our democracy and the legitimacy of our elections lot more, because it brings images of that person not leaving office, and introduces risk of that person turning into a dictator.
The risk amplifies when that sitting President starts using his power to do things that might make it easier to do that also.
