You know what I think is interesting? Here's what:
None of the campaign material from the presidential elections I have witnessed as an adult (1988 - 2004) has prominently featured the image of the candidate. That is, until this year when Barack Obama's image became the focal point of numerous posters, buttons, etc. And not underground material--the official stuff. It's interesting and surely not coincidental that Barack Obama is also the first Black candidate nominated by either of the two principle political parties in the US. Issues of race in the US are so complicated I can barely begin to understand how and why this happened.
Unfortunate PS: as I hunted the web for the images here, I came across a literally ungodly number of horrible and disturbing altered photos of B.O. Let's all rise up... all one or none.
