Someone saw a plausible scenario, ran with it..skewered it..and used it to their advantage.
Was it fraud. I have no idea.
I don’t know the details of how it all went down and what happened after the campaign knew it was false.
All it is is a spoiled child whining because he lost and looking for a scapegoat to cover that fact. Whining about "fraud" just because you lose isn't fighting back, it's just being a poor loser.
