In these perilous days, we must be ready to think the unthinkable. I'm talking about...the quite reasonable suspicion that the Bush Administration orchestrates its terror alerts and arrests to goose the GOP's poll numbers. The 18 months prior to the 2004 presidential election witnessed a barrage of those ridiculous color-coded terror alerts, quashed-plot headlines and breathless press conferences from Administration officials. Warnings of terror attacks over the Christmas 2003 holidays, warnings over summer terror attacks at the 2004 political conventions, then a whole slew of warnings of terror attacks to disrupt the election itself. Even the timing of the alerts seemed to fall with odd regularity right on the heels of major political events. One of Department of Homeland Security chief Tom Ridge's terror warnings came two days after John Kerry picked John Edwards as his running mate; another came three days after the end of the Democratic convention. So it went right through the 2004 election. And then not long after the [elections], terror alerts seemed to go out of style. With the exception of one warning about mass-transit facilities in response to the London bombing on July 7, 2005, that was pretty much it until this summer. Can I prove any of this was politically motivated? Of course not. All the key facts are veiled in secrecy, as they must be. So it's impossible to know from the outside whether it's on the level or not. But with another election looming, it seems we're about to get a bunch of new chances to wonder.
