Obama's entire political career is predicated on him being black.

First, he won office in Illinois from a district of black voters who only put blacks into office. Next, he lost a race for the U.S. House of Reps against a black man in a district that only votes for blacks. After that, Obama won his race for the U.S. Senate against, you guessed it, a black man.

Without the foregoing, Obama never could have run seriously for the presidency of the U.S.

Obama is president precisely because he is black and no other reason, except the money of backers who funded him against a crazy, war-mongering, wrinkly old white guy and his side-kick milf for whom every married guy had the hots that women, the majority of voters were angry about.

Had Obama been white, running in a district that puts into office, anyone, regardless of skin color, few would have taken his craziness seriously and thus, his political career never would have taken off.

And for those who shall cry racist

Men can first attest the word racism to 1932, attributable to use by NAZIs, modeled on the words racialism used in context of South African law, first appearing in 1871.

Racism requires the use of law to inhibit or advance any group that organizes itself along biological lines. Racism is a horrible political doctrine. It devalues every individual and turns persons into monsters as they join groups.

The biggest racists in America today are those organized groups such as the NAACP, NOW, Act Up!, and La Raza, each pushing for privileged spoils from income taxation, privileges like quotas and subsidies.

The biggest promoters of racism in exchange for power are politicians. Racism is a political doctrine. Racism is not bigotry. Bigotry is an anthropological phenomenon. 

A racist act would be organized blacks pushing to get an easing of SAT scores to gain admission into law school. A racist act would be forcing persons to pay taxes and earmarking those taxes to subsidize the hiring of women after an organized group of women have lobbied successfully for such legislation.
