* The 100,000-member Building and Construction Trades Council is leaning toward Peter Vallone.
* The 78,000-member United Federation of Teachers is thought to be behind Alan Hevesi, but president Randi Weingarten is not in a rush to make any announcement.
* The Central Labor Council, an umbrella group headed by Queens Assemblyman Brian McLaughlin, may not make an endorsement in the primary.
* The 27,000-member Patrolmen’s Benevolent Association may not make an endorsement in the primary.
* The 11,500-member Correction Officers Benevolent Association has already backed Vallone.
