The statewide teachers union on Monday announced an “aggressive” independent expenditure program on behalf of its endorsed candidates with the help of $4.2 million in cash on hand.

The New York State United Teachers union has backed a slate of Democratic Senate candidates this election cycle as a broader coalition of labor groups attempt to give the party full control of the upper chamber this fall.

“NYSUT’s VOTE-COPE fund protects our professions, the institutions in which our members work, and the people our members serve,” said NYSUT President Karen E. Magee.

The union has endorsed two Democrats in battleground races on Long Island: Adrienne Esposito and Dave Denenberg. NYSUT is also backing Leroy Comrie, the Democratic primary opponent of Queens Sen. Malcolm Smith, who faces corruption charges.

NYSUT also plans to help the three incumbent lawmakers who are top targets of Republicans: Sens. Terry Gipson, Cecilia Tkaczyk and Ted O’Brien.

“VOTE-COPE will be coming out in force to support candidates that understand the importance of public education and health care and support the values of the organized labor movement,” said NYSUT Executive Vice President Andy Pallotta.

Statewide, NYSUT has endorsed Comptroller Tom DiNapoli and Attorney General Eric Schneiderman. The union, which has publicly differed with Gov. Andrew Cuomo, declined to endorse in the race for governor.
