Advance praise: 'Londregan's book poses a powerful question: to what extent does a quasi-democratic constitution crafted by a military government constrain a liberal electorate from enacting laws consistent with their preferences? In answering this question, Londregan combines state-of-the-art methodology with a deep understanding of the Chilean case. The scintillating analysis of legislative politics in the final chapter is proof positive that high-tech statistical methods are a tool, not a barrier, to compelling narrative. I recommend this book to all comparativists.' David Latin, Stanford University
