If a potentially embarrassing brother is a presidential qualification, it's surprising that Barack Obama doesn't have more to say about George Hussein Onyango Obama.
The Illinois senator mentions his brother in his autobiography, describing him in just one passing paragraph as a "beautiful boy with a rounded head".
As George Obama describes himself:
I have seen two of my friends killed. I have scars from defending myself with my fists. I am good with my fists.
Sounds like George would fit right in with Billy Carter, Roger Clinton, and Neil Bush.
