Over the past few years our body politic has become increasingly polarized: Republicans versus Democrats, conservatives versus liberals. That polarization filters down to governmental actions, policies, and decisions, evidenced in disagreements over regulation versus deregulation and fossil fuels versus renewable energy. Such polarization—whether legislative, administrative, or judicial and whether at the federal, state, or tribal level—can and does impact the management of our archaeological resources and the way cultural resource management is practiced in the United States. Given that most archaeologists in the United States are employed in cultural resource management, these actions affect their employment. Consequently, it is more critical than ever that archaeologists become cultural resource management and historic preservation advocates. This article discusses the whys and hows of preservation advocacy. Active, science-based advocacy by preservationists can engage governmental decision-makers to give due consideration to cultural resources and their management when making decisions or drafting and voting on legislation. Although the discussion focuses on advocacy at the federal level, the observations and suggestions are applicable at the state and local level.
