Lol how can people be elected president of a country just because of skin color? Especially for countries as large as UNITED STATES. Your mind is too filthy, you are too demonstrating your hatred for Obama so you make a statement that makes no sense. Obama was elected because he was a smart man, was elected 2 times is proof.
In 2008, more than 97% of the African Americans voted for Barack Obama, and John McCain got around 2% of the black vote. The stats are self-explanatory. Also, there were racist attacks against white people who put up McCain signboards.
