According to todays The Note, The Communication Workers Union is polling members regarding a possible endorsement in the presidential race. So this may be the next round of Gep vs. Dean w/ organized labor.
Morty Bahr, the head of the Communications Workers has made no secet of his personal backing for Gephardt but is said to be loathe to get out and endorse him given the grass roots support for Dean among rank and file union members.
This is under heading House of Labor
