The democrats can say anything they want to about blacks and the black leadership will not act offended. Why? Because they are afraid of their masters on the plantation (the democrat party). What other reason could there be?
Leadership says nothing to the Democrats because they will vote for Republicans regardless of what Dean says.
The last remaining strength for Democrats is in local elections---city, county, state reps. Nationally, the Dem base is just the re-juvenated Hippie fringe.
