Your taking the definition out of context and basicly re-defining it to fit into your arguement to try and back it up.
1)Betrayal of trust refers to ie: selling of secrets, telling secrets. If your wife were to lie to you, you wouldn't accuse her of treason, would you? So how could you label others as such, soley on a speculation of lying?
2)Speaks for it-self, I don't see how Bush has attempted to overthrow himself, or others in his administration.
