Leaders of some of New York’s most influential unions are discussing abandoning Gov. David A. Paterson as he prepares to run for a full term next year, a sweeping defection that could prove lethal to his hopes of winning his party’s nomination.
The leaders, who represent a broad cross section of labor groups, expressed concern, in a series of interviews, about whether Mr. Paterson, who has been troubled by low job-approval ratings and a loss of confidence in his ability to tackle the state’s financial problems, can rebound in time for next year’s election.
That such conversations are taking place among a constituency that plays such a crucial role in New York Democratic politics signals the tenuous position that Mr. Paterson finds himself in, particularly as Attorney General Andrew M. Cuomo considers the possibility of challenging him in a Democratic primary next year.
