You are right! He is the first half black president. Remember, his dad is from Kenya and his mom is from Kansas.
In my opinion the US is still a bit too conservative and would never \"jump off the deep end\" and elect a full black american for president, we need baby steps. Having a half black president is a step in the right direction towards having a full black president though
EDIT: That video is great. Before I saw this I thought that Dave Chappelle was the first black president.
