Or — and you might want to see if you have the capacity to open you little mind here —
Kari is simply filing a lawsuit about an election in which she has legitimate evidence to point to suggesting that the “irregularities” amounted to depriving her of the justified win.
Protesting an election which might have been conducted so poorly that the wrong person is declared the “winner” isn’t being a bad sport.

And it doesn’t “ruin” our “democracy.” (We
aren’t a democracy, in the first place. And filing such a suit doesn’t ruin our
republic, either.)
Now it’s up to the legal system. If they take the case (instead of misusing some procedural ground to evade the responsibility), the burden will be in the plaintiff/contestant. It is the evidence presented which will tell the story. Not your prejudgment.
