what is civic religion?

are the religious right?
According to Wilfred McClay and William Imboden: That strain of American piety that bestows many of the elements of religious sentiment and faith upon the political and social institutions of the United States. More problematically, civil religion is the misidentification of the nation of the United States with the covenant people of God. It is the casual assumption that America enjoys a special role in redemptive history. It is the confusion of the office of the political leader with the office of the spiritual leader. It is the frequent presumption of divine blessings without submission to divine judgment. It is the sublimation of Christian distinctives to a generic amalgam that conflates many faiths into a common national identity. It is as old as America itself. And it is not biblical Christianity.
