They were, but she still lost, which is why she thinks she was double-crossed.
It’s very simple. Elections are not chattels, because voters are thinking, rational beings, who can take in all the hype and then make their own decisions. So an election can’t be stolen, not by misinformation, not by Facebook adds, and not by revelations. People take it all in, weigh the pros and cons, and then do what they want, not what Google, CNN, Russians or slick ad men tell them to do. Deal with it.
Also by money. All those dollars go for is adverts and parties and such; maybe in the end it buys a vote but not directly.
