Finally, Mrs. Clinton’s aides hope that disclosures about Mr. Obama’s past like the one involving Mr. Wright could give superdelegates’ pause. Mr. Devine said he thought that at least in terms of Democratic primary voters Mr. Obama had turned the furor to his advantage with his speech on race.

“Obama, confronted by an issue that was boiling, seemed to wade into it with a speech that was in many ways profound,” Mr. Devine said. “As a result, now these people who were so interested and awakened by his candidacy are back with him again. Instead of this being a setback, it becomes an opportunity.”

But the audience now is as much the Democratic superdelegates, who are especially attuned to politics and questions of electability in the fall, as it is rank-and-file voters.

Mrs. Clinton’s advisers said they had spent recent days making the case to wavering superdelegates that Mr. Obama’s association with Mr. Wright would doom their party in the general election.

That argument could be Mrs. Clinton’s last hope for winning this contest.
