About this whole Ford/Steele thing, my point would be is that Ford has a larger base of support (in Democrats) he can tap into at present, but Tennessee demographics will hurt him expanding beyond that point.
Simply put, the black population in Tennessee is not that big and I still don't see how Ford, from Memphis, picks up the votes in Nashville and Central Tennessee to get above 45%, above that base of support I mention. If he was from Central Tennessee, I would be singing a different tune, obviously, but a black man from western Tennessee. I don't think it's ever happened in the state honestly (Al can correct me if I'm wrong).
Steele has a smaller base of support in Maryland (a little over 40%), but his being black means that he has a larger potential group of voters (in the black vote), that if he somehow connects with, he can gain votes. I personally doubt that will happen, but he seems to be a fairly smart, articulate black GOP candidate and that is a variable I haven't seen in Maryland recently at least. Alan Keyes does not count towards that.
