They get by with a little help from their friends. Like five years of increase.

So...
1) The CNJFO didn't exist back then. IT is currently operated by people who were just as angered by the dysfunctional spate of 2a advocacy groups NJ has been saddled with since the 91 AWB. There existence seems to have ushered in cooperation and coordination at both the state level and with national entities.
2) The ANJRPC isn't the turd of an organization it used to be. It genuinely seemed to exist solely to waste everyone's time while the NRA mothership used us to drive fundraising elsewhere. It seems to have moved away from that.
Currently I give to those two groups locally, and to FPC, GOA, and SAF nationally. Although I have to say that SAF is on the bubble. They do good work, but are way too comfortable chipping away slowly at things on a single front.
Basically I set aside the price of a case of ammo each year. Around Christmas they each get $25. Then hand out the rest of the funds as I see things I want to back and or fight.
