Maybe Dr. Carson will surprise us by running the kind of campaign that will make us all proud. That’s certainly possible. (If nothing else, this GOP field is already shaping up to be incredibly diverse.)

If it’s the later, that would be especially unfortunate for Dr. Carson. That’s no way to ride off into the sunset.
