The labor group LIUNA-NY on Tuesday endorsed candidates running for the state Legislature, nods that include the backing of candidates in key swing districts for the state Senate.

The group backed Democrats Monica Martinez, Jim Gaughran, Anna Kaplan, John Brooks, James Skoufis and Karen Smythe. And the organization is supporting former members of the Independent Democratic Conference, including Sens. Jose Peralta, Marisol Alcantara, David Carlucci and Jeff Klein.

Among Republicans in potential tossup races, LIUNA-NY is backing Sen. Terrence Murphy as well as Annie Rabbit.

“LIUNA-NY supports candidates that will advance the unionized construction industry, prioritize construction safety, and fight for job creation in New York State. We believe this list of incumbents and challengers sees the value in uplifting middle-class careers in the construction industry.” said Robert Bonanza, Business Manager of the MTDC/Chairman of MTDC PAC and John Hutchings, Director of the NYS Laborers’ Organizing Fund PAC in a joint statement. “These candidates are committed to enhancing safety, wages, and training standards for workers, and we are proud to endorse them in their New York Senate and Assembly races.”

Many of the endorsements tip toward Democrats in part because of the public works bill in the Senate, which had failed in move in the GOP-led chamber.
