Les Deplorables focuses upon Donald Trump's third revolutionary effort to dismantle Franklin Roosevelt's new deal programs of big government that have dominated America since the depression of the 1930s. The first effort was Ronald Reagan's Moral Majority counterrevolution from 1980-89. The second attempt was led by Newt Gingrich's 1994 Contract with America and Republican control of Congress in the 1990s. This book explains the third American revolution in the aftermath of the Tea Party's victory in the 2016 election. The leader of the revolution, Donald J. Trump, can aptly be described as the Tea Party President of the United States. Despite winning the presidency, however, the Tea Party is engaged in a battle with establishment Republican (RINOs) for control of Congress and the media. The outcome of this contest will determine the success of the Trump revolution.

If Trump's presidency is successful in carrying out his Tea Party agenda, Franklin Roosevelt's big government regime will end. Accompanying this revolutionary change will be a realignment of the party system that will likely overthrow the Democrats and make the Republicans the dominant political party under Tea Party leadership. Trump's Tea Party coalition, therefore, threatens the political establishment of both major parties, Wall Street, social elites, and the federal bureaucracy. This fits the classic definition of a revolution in which citizens overthrow the ruling elite. It is comparable to the American Revolutionary War of the 18th Century in which the founders of the new American Republic defeated the most powerful ruling elite in the world - the British Empire.
