This poster is being stuck up around Los Angeles in a guerilla campaign to brand Obama as a socialist. The poster is incredibly visually powerful, and for that reason it has recieved huge amounts of media coverage world wide. It doesn’t really make logical sense, in the respect that the Joker (from Batman) was not a socialist.
But things don’t always have to make sense to have an impact.

Obama is not a Socialist! Obama is a pragmatist and he is definitely not a Communist.
When you have a communist society you are living under different conditions than you are under capitalism. The future where communism will reside will have a highly developed labor saving technology that will allow the production of enough goods and services that will satisfy the society’s material needs with a very small amount of effort. The labor saving technology will free up the time of unneeded workers to involve themselves in producing for themselves and for society’s enjoyment,… art, music, poetry, literature,etc. Arduous labor will be a thing of the past, The political apparatus will no longer be needed and will disappear. Social scientific individuals aware of people around them will voluntarily do for their community what is right and what is social. You will have an administration of things. Not an administration of people.
The Right Wing Crazies are so ignorant they would not know a communist or a socialist if one sat on their face!
