Bingo.
I really doubt the people watching MSNBC instead of checking the CDC website are going to care enough to educate themselves either way.
FWIW, it made Yahoo a day or two ago. People will see (indeed, HAVE SEEN) this to a greater extent than if it were just another "you should have a gallon of water per person per day, plus change of clothes, canned food, and Rx meds" message, and will be at least as likely to actually do something based on it. And it cost no more to make this one than such a bland message would have. That's a win, as far as I'm concerned.
