This is very interesting.... Edwards Becomes A Favorite Among Union Members:

The largest union in the AFL CIO decided Thursday to delay making a presidential endorsement. The delay comes as John Edwards has apparently become of the favorites among union members.

The wait by the Service Employees International Union comes two days after the top contenders spoke to union officials in Washington.

Conference participants were asked to rank their two favorites before and after they heard the candidates. Union president David Stern says Edwards vaulted into the top three candidates within the union after he talked to the members. He pushed out Massachusetts Sen. John Kerry.

....Several union members say they liked Edwards' populist message. He highlighted his working-class background as the son of a mill worker.

Just a few days ago, the news said Howard Dean "wowed them" at their convention.

This is an important endorsement. Gephardt has been a prime contender, then Dean, now Edwards. Looks like it's still up for grabs.
