Or, you know, everyone who was disappointed with the lack of a single-payer system back when the big healthcare thing went through during Obama's first term.
While the two positions are not obviously linked, the people who were in favor of a single-payer healthcare system were from the wing of the Democratic party a lot more likely to favor tighter gun control. Meanwhile, those in favor of the loosest restrictions on gun ownership tend to be from the side of the American political spectrum that thought an insurance mandate was a Socialist practice to be opposed at all costs. It's not a 100% overlap in either case, but it's a significant enough correlation to forgive Karajorma for linking the two.
An interesting point to note, as I go back over Wayne LaPierre's post-Sandy-Hook press remarks again, is that he mentions mental illness exactly once, in a call, not to ensure treatment of their illness, but to ensure proper cataloguing of the mentally ill. So, the official stance of the largest of the United States' pro-gun lobbying organizations is to do nothing with the mental health system, except to demand that doctors violate patient confidentiality by putting those patients in a national database. In fact, LaPierre's thesis was that mental illness wasn't even the problem, but that television and movies and video games have corrupted our youths and so greatly desensitized them to violence that they're more willing to commit violent acts. (If that sounds familiar, it's because it's a stock script that the NRA has been using since the 1990's at least.)
The big reason why, up to this point, I had been talking about the politics of gun control, instead of the politics of mental health reform, is that the people with political clout are talking about gun control. We could, on this forum, come up with a solution to eliminate mental dysfunction as we know it, without any civil rights or budgetary impact on the country, but unless someone on the forum is a U.S. Representative or Senator who intends to take our ideas back to Capitol Hill, it doesn't do us a lick of good. (If someone here is an incognito Congressperson or Senator, drop me a PM, and I'll be happy to discuss any topic you want to bring up.

) At least in discussing gun control, in this period, when politicians are wearing their gun control positions on their sleaves, forum members may give a measure of consideration to what candidates they will support or oppose in the 2014 midterms, if this is a priority issue for them.
