Obama popularity 76% among Hispanics, 85% among Blacks, but only 37% among whites. Why is that?

You include a racist assumption in your question. Actually it is blacks who are more racist than whites. Many of the blacks I know voted for Obama because they erroneously believe him to be black or at least African American.

That itself is racism. To vote for a man based on the color of his skin is nothing but racism. And you further your error by not realizing that at first the approval rating among whites was much higher and only began to drop when his actions ran counter to his stated goals and when his promises were revealed as simple election tactics which he had no intention to honor.

Actually you are mistaken to believe that any conservatives approve of Obama's actions. Obama's acts are decidedly socialist and no true conservative could approve of this man's performance. So in summery your question reveals your own overt racism which you choose to ignore.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
