I am not insisting that you go with that answer, you could also try
The Demon Party and their deranged followers are so filled with bloodlust, than anyone who made progress in exposing the usurper would be murdered. Most likely ritually murdered, but murdered for sure. That's how they roll.
Again you don't have to copy it word for word. If you want to suggest that O and his minions would send a black-ops kill squad led by Hillary Clinton, that would work just as seamlessly - because she is so practiced at murder.

ETA: Oops. Don't say black-ops because the liberals will accuse you of being racist. Maybe a black bag job. No, that doesn't work either. Covert kill team. Yes, that sounds right, the Dems would send a covert kill team.
