Two-thirds of New Yorkers think Governor Corzine of New Jersey should avoid discussions involving redevelopment at the World Trade Center site, a Quinnipiac University poll has found.

Released yesterday, the poll showed that 66% of New York City voters surveyed agreed with their congressional representatives, who last month wrote a letter to Mr. Corzine saying decisions about ground zero should be made by New York. The survey also found that a large majority of city voters favor Mayor Bloomberg, not Governor Pataki, having the “major role in decisions” about the development of ground zero. Mr. Corzine has held greater sway over the future of the site by virtue of his shared control of the Port Authority of New York and New Jersey, the bi-state agency that owns the land.

Political observers attributed the findings in support of Mr. Bloomberg to his continued popularity following his landslide re-election victory. The mayor’s approval rating was at 69%, an impressive number but down from 73% in a poll taken a month ago.

“If you want to get something done, call Mike Bloomberg. That’s the mantra nowadays in New York,” a political consultant, Hank Sheinkopf, said. Mr. Sheinkopf called the new poll a “referendum” on the mayor’s leadership. As the public grows increasingly impatient with the progress at ground zero, the poll is likely to reinforce Mr. Bloomberg’s political standing compared to that of Messrs. Pataki and Corzine. “Pataki is a lame duck, and Corzine is late to the game,” Mr. Sheinkopf said.

Progress at ground zero has stalled amid a dispute between the Port Authority, whose 12 commissioners are appointed by the governors of New York and New Jersey, and the developer who holds a 99-year lease on office space at the site, Larry Silverstein. Messrs. Pataki and Silverstein have blamed delays in negotiations on the New Jersey side. Mr. Corzine, who took office in January and is in the midst of a budget battle with state lawmakers, has criticized the plan for ground zero, as has the Bloomberg administration, and warned about cost overruns at the site.

Rep. Anthony Weiner, who organized the letter to Mr. Corzine from New York’s congressional delegation, said it was “obvious to most observers” that the future of ground zero should be determined by New Yorkers based on the best interests of the city.

The mayor’s office declined to comment on the poll. A spokesman for Mr. Corzine, Anthony Coley, released a statement saying, “A fair deal for the Port Authority of New York and New Jersey is what Governor Corzine is seeking. As negotiations continue that will continue to be his concern.”

Conducted April 4 to April 10,the Quinnipiac poll surveyed 1,316 registered city voters, and had a margin of error of 3%.

More New Yorkers,47%,said the redevelopment of the World Trade Center site was going “somewhat” or “very” badly than the 44% who responded that the process was going somewhat or very well. While two-thirds of respondents said the mayor had played a positive role in the ground zero development, less than a third said the same about the Port Authority and Mr. Pataki, and just 20% regarded Mr. Silverstein’s role as positive.

A spokeswoman for the governor, Joanna Rose, did not comment on the low public support for Mr. Pataki’s role in ground zero, but noted that the “poll shows that New Yorkers support the elements of the master site plan developed by an unprecedented public process – including the memorial and Freedom Tower.”

A majority of respondents voiced support for the memorial and the Freedom Tower, while 61% opposed charging admission to pay for the memorial.

City voters also expressed support for illegal immigrants, as 77% responded in favor of the idea of a program of temporary work visas versus a proposal to bar undocumented immigrants from staying in America under any circumstances.
