Yet, prior research has overlooked the importance of local context, specifically socio-political conditions, and how it can shape an agency’s response to executive-level guidance. We examine the effect of local context on county-level immigration removals by ICE agents from 2013 through 2018. We predict local removals starting with the Secure Communities program, continuing under Obama’s two-year Priority Enforcement Program (PEP), and up through Trump’s zero-tolerance policies. Obama-era executive guidance, which advised agents to target only dangerous criminal immigrants, did lead to a significant national decline in total removals. However, conservative localities continued to remove large numbers, even during PEP. Notably, the difference between conservative and liberal communities was largest for non-criminal immigrant removals. Despite Obama’s guidance to focus on dangerous immigrants, ICE agents continued to remove undocumented immigrants without criminal records from conservative U.S. counties. Our analysis indicates street-level agents are most responsive to chief-executive direction in the absence of local-level opposition to top-down demands. 收起
