Usurper is a better description of Obama, in my humble opinion. Because he is an illegal foreign national occupying the White House, and is not on our side, it better explains why his actions, and inactions, in Benghazi, benefitted the attacking terrorists, more than they benefitted the American defenders. The irony is that the two ex-SEALS killed around 80 of the attackers before they died. On the other hand, the death of four Americans makes Benghazi worse than Watergate, by far, which is why the cover up will never end. Only removing the Usurper from the Office, and from the power it gives him, will allow the truth to come out.
