The NRA donates huge money to politicians. That's why politicians love guns, not because of the constitution.

I think there is validity to the argument that having guns protects you, the people, from your government.

On the other hand, many gun nuts are so brainwashed by right wing propaganda that they would probably shoot themselves if Bush or Rush told them to. Propaganda can be more powerful than guns if it's used correctly, and the right wing knows how to control stupid people.
