There is a cohort of close observers of our presidential elections, scholars and lawyers and political strategists, who find themselves in the uneasy position of intelligence analysts in the months before 9/11. As November 3 approaches, their screens are blinking red, alight with warnings that the political system does not know how to absorb. They see the obvious signs that we all see, but they also know subtle things that most of us do not. Something dangerous has hove into view, and the nation is lurching into its path.
