Policy popularity: The Arizona immigration law

As a maker of policy, a president or a governor invites public approval or disapproval for policy decisions. Public reaction is likely to occur for issues of great salience and clear candidate positions. We focus on immigration policy. Illegal immigration has become a hot issue in recent years, especially in Arizona. The state's governor took a clear stance in 2010 by signing a law that gives police sweeping powers to deal with illegal immigration (Arizona SB 1070). Using an aggregate time-series model, we find that this action affected gubernatorial approval ratings. Indeed the gain in approval proved enduring enough to turn a losing race for re-election into a victory for Governor Brewer. Using individual-level survey data, we find that presidential approval also was affected by reactions to the Arizona Law among residents of the state. When elected officials take clear stances on a salient issue - Governor Brewer for, President Obama against the law-policy moves approval. (C) 2016 Elsevier Ltd. All rights reserved.
