Looking at other RPF polls, the anti-state position does seem to be making gains, but it seems to have slowed down since 2010.
In 2008 anarcho-capitalism/voluntaryism had about 13% of the vote (

I couldn't find any reliable ones in 2009 (one didn't have an "other" option and the choices were poor, one just asked anarchism or constitutionalism or other, and another asked anarcho-capitalism or statist or other) (

In 2010 "Anarcho-capitalist/Voluntaryist/Agorist" got about 36% of the vote (

So, it seems as if it has mainly leveled off since then (assuming these polls are accurate), with maybe slight gains. The "other" percentage is much higher this time though, so it could be greater gains than I expect. It would be interesting to see a poll with maybe "anti-state," "some form of a state," and "other - please explain" as the categories, although I'm sure there would be some disagreement over the terms there as well.
