PACs, issue context, and congressional decisionmaking

Scholars have claimed that PAC influence on congressional behavior is more likely on certain types of issues. After considering both roll-call voting and committee participation, I argue that the conditions making PAC influence on voting most likely make influence on participation least likely, and vice versa. The analysis of 20 legislative proposals indicates that PACs are able to influence voting on non-ideological/non-visible issues, but are more likely to influence participation on ideological/visible issues. Unlike previous studies, these findings demonstrate that PACs can influence behavior across different contexts, but that the route to influence differs depending on the type of issue being considered.
