PAC contributions are the most commonly used indicator to measure the influence of interest groups on legislative votes. This is because PACs provide direct financial support to candidates and lawmakers, which is a tangible way to measure their influence. Other indicators, such as lobbying dollars or the number of interest groups supporting a change, can be more difficult to quantify and may not provide a clear picture of an interest group's actual influence. Interest group staff may also be important, but this is more of a measure of an organization's capacity and resources, rather than their direct influence on legislative outcomes.
