Obama adviser and former CIA warns of pre-election attack: "Brace yourselves"

Bruce Riedel has written a piece in the Washington Post today warning of a pre-election attack from al-Qaeda. He writes:

"If it happened in Spain, it can happen here. The Madrid bombings reveal the close attention al-Qaeda pays to the electoral cycles in Western democracies. Osama bin Laden, the perpetrator of one of the greatest mass murders in U.S. history, is certain to want to have his say in our elections this fall. (Full disclosure: I'm an adviser to Sen. Barack Obama's presidential campaign.) The record is clear: Al-Qaeda has developed a predictable pattern of behavior over the decade since it declared war on the United States that provides important insights into what we can expect in the next six months. Brace yourselves."

The article appears under the heading, "October Surprise." It's probably more "al-Qaeda" propaganda; but I have to wonder if it's a not-so-covert warning that the Bushies are planning something?
