Actually, it's a constitutional republic.
But my real concern here is with the "constitutional" part, because most reasonable readers seem to agree that the PRISM surveillance violates the Constitution. Yet the federal government only seems concerned about Constitutionality when it suits them, (literally) laughing it off otherwise:
CNS: Madam Speaker, where specifically does the Constitution grant Congress the authority to enact an individual health insurance mandate?
Pelosi: [Giggles] Are you serious? Are you serious?”
CNS: Yes, yes I am.
Pelosi: [Takes question from another reporter.]
So I'm concerned that the degree to which we're "consitutional" at all is becoming increasingly tenuous.
