One study - we are not as conservative as legistlators think
It is one study, but at the moment it is the only study finding that legislators, especially the conservative ones, over estimate their constituents' conservatism as much as 20 points. And the mystery of why the bias. The study authors "failed to find any relationship between the amount of time legislators spend in their districts, going to community events, and so forth, and the accuracy of their reads on their districts."
