The American state legislatures provide a unique opportunity for the study of lawmaking. This essay describes and analyzes state legislative research since 1990 and offers suggestions for future research. The discipline made significant gains during this period, expanding our knowledge on a wide variety of important topics and concerns. Despite these gains, many gaps in our knowledge remain unfilled and many questions remain unanswered. The field has been particularly weak in building theory. Scholars need to make a more concerted effort to develop our theoretical understanding of state legislatures for the field to develop greater direction and coherence.the american state legislatures provide scholars with a unique opportunity to study all aspects of lawmaking. These 50 bodies provide significant, but limited, variation on structural, cultural, and political variables that can influence lawmaking, while still being far more comparable than, say, most national legislative bodies. And, indeed, the past decade and a half has been fruitful for research on state legislative politics. Since 1990, the leading scholarly journals in American politics have published more than 200 articles on state legislatures, covering a wide range of substantive topics and theoretical concerns. Many gaps in our knowledge have begun to be filled. The availability of data has improved. Comparative state studies are now the norm, not the exception. As a result, the discipline's understanding of state legislatures and the legislative process in the United States generally has improved significantly. Despite these gains, there are still major areas of state legislative politics that remain largely unstudied. Moreover, many of the problems that have plagued the study of state legislatures in the past continue to do so today.This essay reviews the recent research on state legislative politics.
