Senator Ted Cruz, a former law clerk to the Chief Justice, takes readers behind the scenes of landmark constitutional battles, many of which he himself litigated, and reveals the power of a single Justice to affect the life and liberty of every American-for good or for ill.

When Justice Antonin Scalia was found dead in a West Texas hunting lodge, filling his seat on the Supreme Court became a central, and perhaps the deciding, issue in the 2016 presidential election. For many Americans, it was the most important reason to choose Donald Trump over Hillary Clinton. To many, however, the inner workings of the Court remain a mystery. With an overarching concern for what "the left" may do in the near future, Cruz goes behind the scenes of landmark constitutional battles, revealing the power of a single Justice to affect the life and liberty of every American, including the right to speak freely, to bear arms, and to exercise religious faith.
