Today's raucous revolt against Washington and Wall Street is a classic populist uprising. Now two respected political pollsters show what it means for the future of American politics. The riotous tea parties and town hall meetings of last summer seemingly took everyone by surprise. They shouldn't have. Populist movements have always arisen in times of economic hardship. Here, Scott Rasmussen and Doug Schoen explore the heart of the uprising that has thrown American politics into turmoil. In the past, populist movements have taken root either on the right or on the left. Today's revolt has two wings: a left wing that wants universal health care and a right wing that wants to reduce the power of governmental influence in our lives. Both are hostile to the Washington political class, Wall Street, and the mainstream media -- all of which they consider out of touch with the concerns of ''real'' Americans.
