Don't remember where I heard it, but there's a theory she has 6, one might be an identical twin, and they believe they are a hive-mind due in part to their connection to a powerful demon after going through rites to be a High Priestess of Minerva or some nonsense.

Whether or not that craziness is true, every single politician you know the name of likely has a body double, even if they have to pay out of pocket for them.

Presidents get one by default through the Secret Service. They cannot afford the risk of an international crises more than just a President dying, and there are hush orders on the media like they have for serial killers.

The more the media talks about them, the more likely someone is to take it as a personal challenge to kill the body double just to say they can. No matter about the President, just taking either one out would be some sort of sick achievement.

We will never know how many body doubles actually have perished, because why the hell would they publicize that anyway? They have to secure the illusion of being untouchable, whether or not that's true.

Edit:

If you want credence to the fact that the Cabal worships Minerva, whether or not Hillary is a High Priestess, take a look at the State Seal of California and read this write up about Minerva and the Seal of California:

So consider this: The Great Seal of the State of California, the stamp of state authority and approval, is a demon spirit. Every drivers license, marriage license, state document and so on, is authorized by that demonic symbol. In other words, every place the California Seal is stamped or placed, a curse is referenced.
