Fill them out and send them by all means. While it may not sway her opinion, if all of the NRA members in her district would do so, it would send a powerful message that not everyone believes in her anti-gun BS views. That is always important.
I really wish more gun owners would become NRA members. For the cost of a few boxes of ammo each year, you can be a part of the organization that is responsible for keeping your gun rights intact. Without the NRA, I would hate to see what this country's gun laws would be like today. They may not be perfect, but they are the best chance we have of saving our firearms freedoms. Come on everyone, send in your $35 per year and let's increase the membership and funds to fight these gun grabbers. Just because we have "Dubya" in the Oval Office doesn't mean we should let down our guard. The democrats are trying hard to gain seats in the House this Fall and if they succeed, that's only trouble for gun owners.
