Obama sees support from black community in SC, GA, and AL. WOW. What a surprise

So i've been watching the news, reading the online blogs, hitting the
news sites and one thing that I keep finding interesting is the "news"
that Obama is picking up support from the black community in Southern
states. 

Now, this may be important, but I'm just curious as to why its being reported as surprising in many of the news I see.
