Help?

Okay so maybe I just don't get it. Everyone tired to make the connection of President Obama to the movement of MLK today at the program. I see little connection other then the work MLK. With out we for sure would not be were we are today on the issue of discrimination and other such issues. The only connection I see is this. Because in part the work MLK did has Obama were he is today. Is this it or is there more.

I truly want to understand the connection. Let me know your thoughts.
