Didn’t I read that his father was mostly Arab and only a trace black?

Oh, for crying out loud, just stop it. Any person looking at a picture of Barack Obama Sr. would (sensibly) conclude that he's got far more than just a "trace" of black in him.

Conversely, look very closely, and try to find any "trace" of Arab in the man. I certainly can't.
