Terror Alerts vs Elections

Election Time vs Terrorist Attack
Accusations today over the timings of terror alerts and elections.

The Bush administration used to raise threat levels around campaign time, apparently. Is Obama doing the same with European terror alerts to create a rally-round-the-president effect?

I wondered if there was a correlation between terrorism and elections we could actually see.

See the dynamic graph on Googe Insights

(It tracks the intensity of keywords over time- an interesting barometer of the group mind).

Note: Here I’ve chosen two relevant keywords that have similar intensity. In Insights, if you chose a keyword that’s too intense it dwarves the other and hides the pattern. Example.)

Any correlation?
