The map below presents an interesting analysis from an organization called BillTrack50 (more on BillTrack50 closer to the 2013 legislative session) of the bills passed during the most recent legislative session. The map illustrates which states have the most and least partisan in terms of legislation that passes. New Mexico’s Legislature, which is controlled by Democrats, is not surprisingly a highly-partisan body. According to the report, the only more partisan Democrat legislatures in the nation were California and West Virginia. Several states had more partisan Republican legislatures.
We don’t have historical analysis in terms of this trend, but it would be interesting to see and compare/contrast with economic growth data.
