Tell them they cannot, under any circumstances, ridicule Obama.
we should send them threatening letters...LOL
I doubt very much if they will caricature him anything like Bush. No cross eyes, no large ears big enough to portray him as a monkey No unflattering photos caught at the wrong moment just for humiliation.
The only lampooning of BO will be of His Godhood any other lampooning of facial or physical characteristics would be deemed raciest.
