...
What worries many Americans ... is that the authoritarians can excuse their excesses as the necessary response to an enemy that every American knows to be real. For the past five years, the Republican leadership has argued that the attacks of September 11, 2001 -- and the continuing threat from jihadist groups such as al Qaeda -- demand permanent changes in American government, society, and foreign policy. Are those changes essential to preserve our survival -- or merely useful for unscrupulous politicians who still hope to achieve permanent domination by their own narrowly ideological party? Not only liberals and leftists, but centrists, libertarians, and conservatives, of every party and no party, have come to distrust the answers given by those in power.
...
The question that we face in the era of terror alerts, religious fundamentalism, and endless warfare is whether we are still the brave nation preserved and rebuilt by the generation of Sinclair Lewis -- or whether our courage, and our luck, have finally run out. America is not yet on the verge of fascism, but democracy is again in danger. The striking resemblance between Buzz Windrip [the demagogic villain of Lewis's novel] and George W. Bush and the similarity of the political forces behind them is more than a literary curiosity. It is a warning on yellowed pages from those to whom we owe everything.
