"What makes elections and transitions so attractive to terrorists? After the October 2004 Bin Laden video was released, I wrote here about jihadists’ need to leave their fingerprints on big events. These are the seam moments, the points of inflection in history, and the terrorists want to demonstrate that they are central players in determining outcomes. They especially want to show their Muslim audience that they are having a powerful impact on the world stage and are the global actors they claim to be. Do they try to tilt events to help preferred candidates or parties? There isn’t much evidence to support that—and the terrorists seem to have some regard for the law of unintended consequences, so I don’t think they believe they can act with sufficient precision to ensure, for example, a victory for McCain or Obama."
