Why do I toture myself by reading the “journalism” on CNN.com?
From the CNN.com article:

Seventy-four percent of the 1,033 adult Americans polled said they believe an attack is being planned, according to the poll conducted by Opinion Research Corporation on behalf of CNN.

Well. There it is. Now you know.
I’m curious to know the reasons behind pollees’ beliefs. Perhaps Joe and Jane Average from Middle-of-Nowhere America should get senior level intelligence jobs in the US government since they gots the 411 on Osama.
Or more likely – this CNN article achieves nothing at all, journalistically or otherwise.
This poll is about as useful as asking a person in rural America who works at Home Depot whether they consider dark matter a threat to alternate gravity theories.
