Who Votes for Natural Resources in California?

California is home to a long tradition of direct legislation, stretching back to 1911. Since then, more than 70 environmental policy measures have been placed on the statewide ballot. The vast majority of these measures have been concerned with natural resource (wildlife, land, water) management. Drawing on county-level returns, electoral returns, and surveys, this article uses ecological inference and logistic regression to show demographic and partisan patterns of support for environmental measures. Despite controls for various demographic and partisan characteristics, spatial differences in voter approval persist.
