Barack Obama (born August 4, 1961 in Honolulu, Hawaii) is the 44th President of the United States. He was in office on October 21, 2015. Originally, in Timeline 2, there was a Female president in 2015. However, after Marty decided not to race Needles in Timeline 8, the future became uncertain. Presuming the world events of Timeline 8 correspond to those of real life, this resulted in Obama being President of the United States instead of the unknown female by 2015.
In 1955, Lou Caruthers was skeptical at the idea of there being a colored mayor in the future, yet by 1985, Goldie Wilson had become the mayor of Hill Valley. Similarly, in 1985, the idea of a colored President of the United States was still largely seen as a distant fantasy, yet Obama defeated this notion when he was elected in 2008.
