Check out this interview of Mick Huckabee:
The Today Show Interview with Mike Huckabee
"That floating cross is a bookshelf...We were all amused, probably the production crew more than anyone"
"So you didn't see that image when you put that spot together?"
"Absolutely not....somebody is going to figure out that as I was blinking my eyes I was saying some special code, Morse code and telling people a subliminal message. It is just beyond ridiculous..."
Now when you first saw that ad did you see that cross in the background?
I saw that cross right away.
How could everyone on the Huckabee staff miss something so obvious. These ads take a lot of time to put together and are inspected very carefully.
If you aren't scared about Huckabee yet check out this internet ad (not from the Huckabee campaign).
