And 99.9% of her secret service agents hate her guts. I’m sure they would help in this matter.

You don't think She Who Must Not Be Named cannot demand who is and who's not on Her detail? There are Clinton apparatchiks in every department, and that includes DHS (who now runs the Detail).
If I were a current candidate for President, I would NOT trust the USSS detail. I'd get my own posse to watch my back. Take Barack Husayn ibn Mahomet, for example: he could easily get some Nation of Islam muscle at any event he asks for.
