Check out a very good article on Obama and the cult of personality.
Here is a brief passage:
The pervasive nature of President Obama’s image is something new and quite different in American presidential politics. When President George W Bush came to office you could maybe get a mug, a commemorative coin or a button, but even his most ardent supporters did not adorn themselves with his image. True, some did sport Stetsons, but that was about the extent of the personality cult around the previous occupant of the White House.
In contrast, today our new president’s image is everywhere and yet no one seems to find this strange or creepy. During the Cold War, American politicians used to vilify communist countries for the cult of personality that surrounded their leaders. But Maoist China and Stalin’s Russia have nothing on Obama’s America when it comes to the cult now surrounding the new US president.
