This document summarizes the history and influence of lobbyists in California politics. It describes how lobbyists represent thousands of interest groups affected by state policies and work to craft beneficial legislation. In the past, powerful lobbyists like Artie Samish were able to ensure regulations protected their clients, but now legislative leaders decide how lobbying money is distributed. Major industries that hire lobbyists include health care, technology, energy, and local governments. The document provides examples of lobbying expenditures by groups like PG&E, the city of Atherton, and Google. Many lobbyists are former elected officials or legislative staffers who leverage their expertise and connections.
