You probably didn't read the post carefully.
The maddox=miller=segregationist slur was slyly implied (even as it was being denied) by David Gergen as per kerry-dnc talking points.
Susan Estrich and David Gergen must be on the same talking points email list. Or what do I know? Maybe they created this talking point.
It was an obvious down and dirty, mean, nasty attack, I have to think it will offend the intelligence of all but the most demented voter.
