Obama And Sheldon: Seperated At Birth?

  

Only recently, I have begun watching the "Big Bang Theory" and it seems that the character, Sheldon, closely resembles President Obama.
Some comparisons:
Sheldon is white, Obama pretends he is white.
Sheldon is a college professor, Obama was a college professor.
Sheldon is a big narcissist, Obama is a huge narcissist.
Sheldon is book smart but socially stupid. Obama is book smart but is socially stupid.
Sheldon doesn't drive and needs people to drive him around.  Obama relies on the Secret Service to drive him around.
Sheldon has trouble with women, Obama is rarely seen with Michelle and they go on separate vacations and don't even travel to the same location together.
Sheldon loves super heroes, Obama thinks he is a Super Hero.
Sheldon is not athletic, Obama isn't very athletic except in basketball and that is even suspect.
Sheldon talks big but in reality says little.  Obama talks big, says little.
Sheldon has few true friends.  Obama has few true friends.
Very few people respect Sheldon.  Very few people respect Obama.
Finally:
Sheldon: It's all about me.  Obama: It's all about me.
