Want to get national attention and actually accomplish something? Join 20 million armed people marching on DC the day after Hussein has overturned the 2nd amendment.
While indeed a great idea, as we know the chances of a 'march' like that happening are less (not impossible, but less) than 25 Citizen Grand Jury's from numerous states doing what GA did.
Either way, national attention is what's required to bring about action on this... outside of the conservative web sites, a few 1 hour programs on a few conservative radio shows, and occasional left wing site ridicule of the issue.
