It actually helped us in the Recall Morse efforts that we DIDN'T have any visible support from the NRA because Morse accused us of being NRA shills and had to eat a lot of crow when it turned out the only thing they did was send out a postcard mailer to all members in the area. I think they knew what they were doing -- or weren't -- and acted appropriately.
The NRA was there meeting with legislators. Again, as with the recall efforts, the gun control zealots were accusing protestors of just being a front for the NRA so I think they wisely took a step backward and spoke but let the public see it was common citizens who were against the gun control legislation rather than this "weapons lobby" boogeyman the banners keep talking about.
