The very latest survey, released by Pew on August 26th, ups that to 44% of all households, see http://www.people-press.org/2016/08/26/opinions-on-gun-policy-and-the-2016-campaign/ http://www.people-press.org/2016/08/26/opinions-on-gun-polic... for the executive summary and up in the right hand corner the full release with that number http://www.people-press.org/files/2016/08/08-26-16-Gun-policy-release.pdf http://www.people-press.org/files/2016/08/08-26-16-Gun-polic... Survey size was a bit over 2,000, so if they got a good sample, which is getting harder and harder, it ought to be a solid number (most national political surveys are half that size, 1,000 is considered to be a minimum for any degree of accuracy). That percentage goes up and down depending on people's willingness to admit that to a nosy surveyer; RKBA activists attribute this recent increase to the huge numbers of first time owners who haven't yet decided on a policy of discretion. Me, I wonder how many of us longer term owners have adopted a FU attitude in the presidential campaign with the starkest choice ever presented to us, excepting perhaps G. H. W. Bush vs. Dukakis, but Bush the father was much closer to total prohibitionist Dukakis, and in fact we're still living with his import bans.... You are of course right that a list of suspected gun owners could be generated in a whole bunch of ways, although I note that when it comes to online ammo dealers I've never seen a group of vendors who are faster in discarding their records of past sales.
