Here's the link to a fascinating study by RPI http://news.rpi.edu/update.do?artcenterkey=2902
It ties in nicely with some of things Michael Bane has said about the change in the culture toward guns. In a nutshell, if 10% of any given population accepts your idea, it will spread like wildfire. This is not really new news but it provides evidence to what the great political masters have always known.
Sorry FA, but this is one of the reasons I think quantitative political science is pure BS. The "science" says it takes ten percent of a given population to tip the scales. Really? Well that explains why most Americans must be both pro-life and pro-choice, Christian and agnostic, gay and straight, pro-gun and anti-gun, PC and racist, like chuncky and creamy, and chocolate and vanilla and the list goes on. At least ten percent of the populace are hard core believers in two diametrically opposed positions. A and not A, logic, and looking outside the window, tells us this can't be true if the theory is correct. Ergo, the theory is wrong under normal conditions. But that does not deter the quantoids.

This BS nonsense that you can do an experiment in a lab and have it mean anything is killing my discipline. Because hey, they used math and the answer is 47 so it must be true. Ignore the guys who don't think you need math to say something useful about politics or history. What do they know? AAAARGH!

FQ13 who obviously has some issues here.
