Lets ask someone who actually lives in Oklahoma, if Obama's skin color is an issue, shall we?
Most Americans know little if their own history and most don't know that on June 1, 1921 the US Government BOMBED the Greenwood section of Tulsa, Oklahoma, known as the Black Wall Street because of the prosperous and booming business district. The night's carnage left some 3,000 African Americans dead, and over 600 successful businesses lost. Among these were 21 churches, 21 restaurants, 30 grocery stores and two movie theaters, plus a hospital, a bank, a post office, libraries, schools, law offices, a half-dozen private airplanes and even a bus system.
They don't teach this to American children and the adukts don't want to know.
There is little question that much of that same tension exists in Oklahoma today. Even JC Watts recognized that he would not win state-wide election in Oklahoma.
However, the racism in Oklahoma doesn't just extend to blacks because American-Indians and hispanics aren't represented in Oklahoma politics either.
Obama not doing well in Oklahoma is no surprise.
