==CHICAGO, Aug. 8 — The A.F.L.-C.I.O.’s executive council voted on Wednesday against endorsing any presidential candidate, reflecting divisions over which Democrat to support and setting the stage for its 55 member unions to make individual endorsements.
Labor leaders said several large unions were leaning strongly toward Senator Hillary Rodham Clinton of New York and others toward former Senator John Edwards of North Carolina.==
==Union leaders say two giant public sector unions, the American Federation of Teachers and the American Federation of State, County and Municipal Employees, are leaning toward Mrs. Clinton. But the strong support that those unions’ locals in the Midwest feel toward Senator Barack Obama of Illinois could prevent their parent unions from backing Mrs. Clinton.
Many industrial unions, most notably the United Steelworkers, are especially enthusiastic about Mr. Edwards because of his backing of many labor causes and his strong views on limiting international trade accords. Union leaders say there is a good chance that the Teamsters and Unite Here, which represents apparel, hotel and restaurant workers, will back Mr. Edwards.==
