A 501(c)(3) basically gets "public money" in that donations to same can be written off on your taxes as a charitable donation. So if you donate, say, $5k, assuming you're in a fairly high tax bracket you'll get around $2k back off your taxes ("public money").
Which is why that tax status CANNOT do overt electoral politics ("candidate politics") at all, can do only minimal "issue-based grassroots politics" making up only a small portion of the group's finances and have other such limits.
Gun-rights 501(c)(3)s include:
* Main NRA (funding range safety issues, rangemaster/instructor qualifications, target shooting activities and the like).
* Second Amendment Foundation
* Jews for the Preservation of Firearms Ownership
The first two are part of "sets" with other members of the set NOT limited in terms of more overt political activities (and with separate financing). As JPFO's primary mission is education related to the link between gun control and genocide, they do their thing within the legal limits of an educational organization.
Donations to a 501(c)(4) are NOT tax deductable, so with no "public support" they can do more overt politics. Which is why I'm paid out of such funds (CCRKBA).
501(c)(4)s include:
* CCRKBA
* NRA/ILA ("Institute for Legislative Action")
* Gun Owners of America (and their California subsidiary, Gun Owners of California)

501(c)(3)s by their nature are more efficient at fundraising. I'm on the board of directors of a 501(c)(3) - see also
www.blackboxvoting.org - we organized that way to get the funding needed to investigate wrongdoing in voting of all types, particularly electronic/touchscreens. We can publish info on what both government and private companies are doing in this field, and if people decide that a gov't official is screwing up based on our data, they can do as they will. We won't be able to say "don't vote for this person" but with enough data, we won't have to.
I'm using BBV as an example to avoid trying to "talk up" any one gun group in the above lists but the point is the same over in the gun world.
A case can be made that this poll is...well, counterproductive. What I mean is, it's unlikely anybody will label the Pink Pistols as THE most critical org but I'm here to tell you: they help. A *lot*.
Similar statements can be made about ALL of the above orgs and more, even if you don't consider them "tops".
-------------
Final note: I'm educating y'all as to the different types of orgs because the gun-grabbers do the same things, and they have a track record of screwing it up...and can be *seriously* damaged as a result.
