McCain believes all politicians are inherently corrupt and must be controlled (by the corrupted governing body, btw). That was his excuse when he was one of the "Keating 5".
This is a frightening peek into the soul of John McCain.
It's McCain's "Stop me before I kill again" defense.
Our forefathers also believed that all men are inherently corrupt, that is why we have a system of checks and balances. Of course that system is only effective when the first ammendment actually provides truthful information about what our government is doing.
This is an arguement for more free speech rather than less. That makes John McCain even more frightening.
