PG's graph is from a battery of questions about very general things, like whether there should be a better safety net, immigrant friendlier policy, stricter environmental policies etc. Even if voters didn't change their policy opinions, it could be that as the elected officials veer further right due to lobbying or whatever, and then citizens have more stern answers to this poll as the actual enacted policies get more divorced from voter opinion.
