As a supporter and admirer or Alan Keyes, I think this is one proposal he can afford to back away from.
There are sound arguments against it, the primary one being that the tax cuts would go to *descendants* of slaves.
Still, I don't understand why some "conservatives" disagree with Keyes on much bigger issues like abortion, even going so far as to say they'll vote for Obama.
Why do they hate Keyes so much?
At some point Alan has probably managed to gore their sacred cows.
