Heres my take on this whole issue about "getting involved" I think a lot of people try to go the politcal route get frustrated and stop do to getting burned out really really fast. By all means if thats what you want and you have the stomach for politics go for it.
I look at it a differn't way, if you really want to change somebody's mind you have to change their heart. I've found the easiest way to get somebody to change their side is to take them shooting. If you want to take it a next step. Become an Instructor yourself and join up with a local club or CCW crew and start teaching not only to better your own knowledge but to have a positive impact. Take this guys for example they are a political group but have HUGE impact among youth and women

These guys up in Wisconsin are FREAKING incredible when it comes to serving the public intrest/changing opinions.

They not only run sports camps but run the USMC Poolee program. Introducing "Poolees" how to operate an M16 style Rifle before going to boot.
Don't get me wrong the lobbying side is very much needed. But teaching people (expecially women: they decide if there is a gun in the home) the correct way of doing things is what really makes the lobbying side.
