Doctor Who during season four had a mid-season trailer that played during 2008

It tells about the darkness that is coming. At the end of the trailer you can see a silhouetted figure approaching. This character is Davros, leader of the Daleks which were modeled after the Nazis.
Whether the script writers realize it or not I think they were giving a warning to the public about Obama.
