About 40 years ago, a social movement arose to destroy the establishment. The people we loosely call the New Left wanted to take on The Man, return power to the people, upend the elites and lead a revolution.

Today, another social movement has arisen. The people we loosely call the Tea Partiers also want to destroy the establishment. They also want to take on The Man, return power to the people, upend the elites and lead a revolution.

There are many differences between the New Left and the Tea Partiers. One was on the left, the other is on the right. One was bohemian, the other is bourgeois. One was motivated by war, and the other is motivated by runaway federal spending. One went to Woodstock, the other is more likely to go to Wal-Mart.

But the similarities are more striking than the differences. To start with, the Tea Partiers have adopted the tactics of the New Left. They go in for street theater, mass rallies, marches and extreme statements that are designed to shock polite society out of its stupor. This mimicry is no accident. Dick Armey, one of the spokesmen for the Tea Party movement, recently praised the methods of Saul Alinsky, the leading tactician of the New Left.
