I don’t necessarily believe that all correlation is more than coincidence. But here are a couple of really interesting entries from Julius and Biltud over at JuliusBlog:

This one shows the correlation between Bush’s approval rating and terrorism alerts:
Chart: Bush Ratings vs. Terror Alerts
Remember, though, that correlation does not imply causation.

And this entry details the timelines of alerts and how they relate to the national news headlines in the days just prior to the alert:
Timeline of Terror Alerts
I find this one less compelling, simply because it lists only headlines that were not flattering to the Bush Administration, and lists only headlines before each terror alert. It would be interesting to see what else was going on in the news at that time, both before and after each alert.

There’s a lot of info here, and it’s well worth checking out!

Not political? Suuuuuuuure. I have a hard time believing that. It’s also going to be hard to prove, though.
