This mostly restrictionist trend reached an important pivot in 2012. Three major developments prompted this change in direction and momentum. First, the U.S. Supreme Court issued its Arizona v. United States opinion, delivering its most consequential decision on the limits of state authority in immigration in three decades. Rejecting several provisions of Arizona's controversial omnibus immigration enforcement bill, SB 1070, the opinion nevertheless still left open possibilities for state and local involvement. Second, President Barack Obama, against the backdrop of a stalemate in comprehensive immigration reform (CIR) in Congress and contentious debates over the role of the federal executive in immigration enforcement, instituted the Deferred Action for Child Arrivals (DACA) program, providing administrative relief and a form of lawful presence to hundreds of thousands of undocumented youth. Finally, Mitt Romney, the Republican presidential candidate whose platform supported laws like Arizona's and called them a model for the rest of the country, lost his bid for the White House with especially steep losses among Latinos and immigrant voters. After these events in 2012, restrictive legislation at the state level waned in frequency, and a growing number of states began to pass laws aimed at the integration of unauthorized immigrants. As this book goes to press, this integrationist trend is still continuing.
