Assess students' ability to analyze constitutional federalism by evaluating conflicts between state and federal law, focusing on the Supremacy Clause and preemption doctrines. Using case studies of marijuana legalization and sanctuary cities, require identification of constitutional issues, application of relevant precedents and federal statutes, analysis of express/field/conflict preemption, prediction of likely legal outcomes for hypotheticals, and formulation of reasoned legal and policy conclusions about state sovereignty and federal enforcement.
