The Supreme Court's 2010 decision in Citizens United v. Federal Election Commission dramatically restructured how American elections are funded by gutting restrictions on corporations' ability to give money to political candidates. One of the most impactful resultant changes was the rise of the super PAC, a new kind of political action committee that could raise exponentially larger sums than its predecessors by channeling corporate donations. Although the full significance of super PACs will not be known for several election cycles, this study is a fine initial exploration of how they have altered the American electoral landscape. Smith and Powell compartmentalize their approach by detailing and analyzing the role that super PACs played in the Republican presidential primaries, in President Obama's preparations for his reelection bid, and in the general election for president. . . .In addition, the authors separately scrutinize candidate-affiliated super PACs and independent ones. While many of the accounts in this slim monograph are brief, they are highly informative and readable, and can serve as an excellent introduction to the subject for students and scholars alike. Summing Up: Highly recommended. Undergraduate collections all levels and above.
