Precisely. If the race of the candidate were the deciding factor for black voters, that would be true. But it's not - an Obama running as a Romney clone on the GOP ticket would get 10% of the black vote.
They support him first because of his welfare socialist giveaway programs. Being black is just icing on the cake.
Blacks would not give Allen West 10% of the vote if he were on top of the GOP ticket instead of Romney. 90% of blacks are democrats because of socialist programs. Never forget that Bill Clinton and Al Gore got about as many black votes as the Kenyan candy man. Also never forget that the Kenyan can get 100% of black votes and Romney can still be elected.
Whites elect the president. Whites outnumber blacks by 70% to around 13% of the total population, but if you were to look at American sports and entertainment you would think the percentages were the other way around. For the last 30 years the majority of blacks were born to unwed mothers and had no father figure in their life so they looked up to athletes as role models. You still see very few in highly technical fields, such as doctors, nuclear engineers, or aircraft pilots. The reason for that is the breakdown of the nuclear family and the democrats keeping them dependent on the government instead of self-reliance.
