Slight lead for Hillary susceptible

Democratic party strategists said yesterday that, with the race so close between Mr. Obama, of Illinois, and Mrs. Clinton, of New York, it was possible that the party's superdelegates could decide the nominee.

"If it's that close in those remaining primary and caucus states and the delegates are about evenly split, [superdelegates] could decide this," said Jim Pederson, the former Democratic state chairman of Arizona who is backing Mrs. Clinton.

Mrs. Clinton has about 1,045 delegates, including 261 superdelegates, of the 2,025 needed for the nomination, according to ongoing counts by the Associated Press and the two campaigns. Mr. Obama has about 960 delegates, including 202 superdelegates.

Superdelegates, an array of members of Congress, governors and state Democratic National Committee (DNC) members, are free to support who they like at the party's nominating convention — unlike pledged delegates allocated based on nominating contests.

And with more than the half the roughly 800 superdelegates committed, both campaigns are furiously courting the remaining votes.

"We would like to get as may as possible, though we don't have a definite ceiling to what we're shooting for," said Clinton spokesman Phil Singer.

One of the superdelegates, former DNC Chairman Steve Grossman, said they may be a deciding factor in crowning the Democratic nominee.

"And as such I think many of them are likely to remain undecided for a significant period of time, waiting for a lot more results to come in," Mr. Grossman said. "They may very well go through the big states to come until March to see how this shakes out and then make their decision."

The party created the system in the 1980s to open it up to wider voter participation. Officials at the time wanted its party leadership and hierarchy to share some of the nominating power that was being shifted to its party members at the grass roots.
