I have been unable to find that quote independent of Engelhard. *IF* it is a real quote, it is most damning thing I've heard from any Democrat, including Jesse Jackson and Al Sharpton.
Personally I think the Dems=Nazis comparison is not only illegitimate, but unproductive. Still, the author is clearly making it, Im not saying that Mitchell and Clinton are Heydrich and Eichmann not being credible.
