Since the late 1960s, the number and types of organized interest groups working at the state level have increased dramatically, but research shows that traditional organized interest groups, such as business and labor unions, are still the most influential in state policymaking (Thomas and Hrebenar 1996). Less is known, however, about the influence of non‐economically focused interest groups in the state policy process. Using pooled cross‐sectional data from the American states, I explore the effect that nontraditional organized interests can have on state policy. Specifically, I examine the influence of the Humane Society of the United States on state adoption of animal cruelty felony laws. Although the Humane Society is not one of the traditional groups expected to have a significant influence in state policymaking, my results suggest that it has played a significant role. However, I also find that the Humane Society's influence on the stringency of these laws is less pronounced.
