TRENTON, N.J. -- Some of the superdelegates from New Jersey who have said they will support Sen. Hillary Rodham Clinton now suggest they could end up supporting Sen. Barack Obama.

The lawmakers suggested they might be willing to change Monday at an event in which New Jersey Sen. Frank Lautenberg announced his intention to run for another term in the U.S. Senate.

Among those superdelegates in attendance were Rep. Donald Payne, Rep. Steve Rothman and Rep. Rush Holt. Payne supports Clinton, Rothman supports Obama, and Holt is uncommitted.

With Clinton trailing in both the national vote and delegate counts, Obama is pushing to get more superdelegates, including Democratic National Committee member June Fischer, who was wearing a "Supers for Hillary" button Monday.

"I think the popular vote will probably, certainly be a major factor, and delegate lead," Fischer said.

Her comment is significant because Obama has a 2.5 percent lead over Clinton in the national vote count, and a delegate lead of more than 100.

Gov. Jon Corzine, another superdelegate who has strongly supported Clinton, also said those factors were the most significant -- suggesting he could switch sides after the end of the primary season.

"The ones that are the most important, in my view, are the popular vote and delegate count," Corzine said.

Another Clinton superdelegate, New Jersey Democratic Party Chair Joe Cryan, said he could see himself switching to Obama.

"If she loses all the other states post-Pennsylvania, certainly we would weigh that," he said.

As for Lautenberg, he said he had no problem with the contest between Obama and Clinton continuing.

If the sampling of New Jersey superdelegates is representative of Democrats elsewhere, the party could be closer to settling on a nominee than many pundits think.
