Beck is building solidarity and cultural confidence in America, its Constitution, its military heritage, its freedom. This is a vision that is despised by the people who have long held the commanding heights of the culture. But is obviously alive and kicking.
Beck is creating positive themes of unity and patriotism and freedom and independence which are above mere political or policy choices, but not irrelevant to them. Political and policy choices rest on a foundation of philosophy, culture, self-image, ideals, religion. Change the foundation, and the rest will flow from that. Defeat the enemy on that plane, and any merely tactical defeat will always be reversible.
