This paper examines the effects of interest group Political Action Committee (PAC) spending on the passage of the Agricultural Act of 2014. I use a mixed-process model to examine correlations between ideology, constituent characteristics, and PAC contributions by agricultural and environmental interests and the probability that a legislator voted in favor of the act. I find a positive association between agricultural and environmental PAC contributions and the probability that a legislator voted in favor of the act. Further, I find that legislators representing relatively large rural populations were more likely to vote in favor of the act.
