I don't know, d-m.
It seems contrary to everything we've seen from unions in the past.
The idea that they put A Greater Good - in this case, the Democrat Party's being in power (which they see as good) - over their own self-interests, seems far-fetched.
It's seemed to me that the unions are the Dems' b**ch because the Dems give them what they want.
I just can't see their being idealistically loyal and putting The Party's interests ahead of their own.
(When did I become SO freakin' cynical!!)
